IChat lost connection to AIM!?!?!?!

Everytime I try to go on to iChat this message pops up "iChat lost connection to AIM. The connection to the host was unexpectedly lost." Any help?!?!

Help! I've got the same problem and I've tried - port 443, 1080, 5091 and neither works. I can ping the aol server, use msn, but I cannot connect to AIM with ichat or with the standalone version AIM 4.7 for the mac. The web version doesn't seem to work either. I started a new account and i got the same error message at login - could not connect to aim - the connection tot he host was unexpedtedly lost. I am at a school, but the network guys have said that the application isn't being blocked and the ports should be open. I have a wireless macbook with os x tiger and a wired imac intel with os x tiger and neither work. any suggestions?

"Lost Connection with AIM" repeatedly

Hi there,
I'm using a new Linksys WRT54GL router with the DD-WRT v23 firmware -- which is otherwise fabulous, by the way -- but since going with the router iChat has been pretty unreliable. I can't connect to my sister in England (I'm in Canada): we keep getting "insufficient bandwidth" errors (I'm on a very hi-speed cable internet connection, so I don't think it's me!). Moreover, AIM frequently kicks me off iChat with the message "Lost connection with AIM".
I've configured my router using instructions linked from this forum. I'm forwarding the following ports to my computer:
5060
5190
5220
5222
5678
16384
And while I can connect to other users okay (except my sister, it seems), staying connected it a real issue. Can anyone recommend a fix?
Thanks,
Aaron.

Hi Aaron,
This last port should be a group of 20 ports (16384-16403)
iChat needs 4 ports from this group to do 1-1 Audio or Video chats.
Many Linksys have UPnP. It is found in the Administration tab. If you have this you could use this. Disable the Port Forwarding if you do.
Also port Forwwarding points to one IP/computer. If this is the case for you and you still have the device doing DHCP there is a cance you computer's IP has changed if it goes to sleep or is shut down when the lease time runs out.
Check this on your computer and the Port Forwarding settings.

"Lost connection with AIM" error message

Hi all,
I've been a long-time iChat user — I've had very few problems, but now, at home, whenever I've been connected for about 10-15mins, iChat just disconnects with the simple iChat Connect Alert that the app has "Lost connection with AIM. The connection with the host was unexpectedly lost."
My Buddy List collapses to a "disconnected" header and I diappear from my Buddies' buddy lists. If I'm in the middle of a chat (video, audio or text), the chat continues uninterrupted, but I still disappear from people's lists as if I'd disconnected manually. Weird.
The net result is that I have to keep checking to see if I'm connected and then reconnecting all the time. A real pain in the proverbial.
It only happens at the house. My laptop doesn't disconnect if I'm at the office, for instance.
I have cable, coming in to Netgear 814v2 router; out to an 8-port gigabit switch, which then feeds my three main machines. All via ethernet cabling.
All machines have the same problem described above.
I've made the usual Quicktime setting changes.
I've listed the necessary ports in my Mac firewall settings (even though the firewall is turned off).
Each machine has a dedicated IP issued by the router (10.0.0.2 thru 10.0.0.5)
The router firmware is up to date.
What else is there?! I have no problems initiating or joining any sort of chat with my buddies around the world. I have excellent bandwidth. My internet and email are never interrupted 24/7.
Can someone help me? Pretty please?

Hi
Try this log on to AIM on port 443 rather than port 5190
Go to IChat > Preferences > Accounts.
Log out of AIM and then use the Server Settings tab
Set the port to 443.
Log back in again.

IChat "Lost Connection" | iTunes "-50 Unknown Error Occurred" Problems

Hello Everyone!
Since installing a wireless network in my house my MacBook Pro is having problems. Now, iChat won't connect and just says "Lost connection with AIM" as soon as I attempt to connect, although AOL Instant Messenger works perfectly. Also now when I am trying to purchase music through iTunes it says "-50 Unknown Error Occurred" and it recommends for me to check my network connection. The wireless connection is working fine for internet browsing but I am having all of these troubles with other programs. I am extremely confused. My network is WPA2 Personal, and I'm running 10.4.8. Please help!

Thanks for all the help.

Hi Irobin,
I am puzzled by this at the moment.
Deleting the .plist file would normally sort this.
Can you create a test Mac User account on your Mac.
Set up iChat with exactly the same Screen name in this new account.
Does this work ?
You will only see the screen names unless you export the other (Mac Account) Address Book details and import them into this account's one. This can be done though the Backup option the Address Bok has.

IChat Lost Connection

My iChat will connect and seem to be normal for a few minutes, but then it disconnects without my knowledge. I just stop getting messages or it will show a buddy speaking, and I just sit waiting for them to say something. People think I keep leaving chats, when really I have no idea I have gone away. Sometimes it will come up with a "lost connection" message.
I have tried changing my port from 5190, and have used the Interference Robustness setting. Neither worked.
I am also using Wireless if that helps, but my roommate using the same wireless connection seems to have no problem.
Please help! This is driving me crazy.

Try changing the channel on the router.

IChat cannot connect ot AIM

trying to set up iChat on an (old?) PowerBook G4 (Mac OS X 10.4.11), iChat v3.1.9 every time iChat starts up and tries to connect a window opens telling me that the AIM login failed (wrong Pseudonym {screenname} or Password).
During setup I have choosen *.Mac account* and entered the MobileMe ID (ending on @me.com). In the window I see that this has changed to @mac.com.
On the same PowerBook there is another user installed and that one worked perfect: connection through .Mac and having the same @mac.com endings. This account is about three years old (no MobileMe then). The newly created account is a family account and was created with @me.com
I have also created an AIM account right now and adding that account to iChat allows me to connect to AIM without a problem. Therefor I assume that my software on the PowerBook is ok but there must be something wrong with the handover from iChats MobileMe data to AIM.
Unfortunately I have no idea what I have to change, can anyone help? Thank you.

Hi,
As you know the .Mac service when it ran did much the same as MobileMe does now.
For iChat though there was one difference in that trial or even a lapsed Paid For account could continue to be be used in iChat.
In Leopard when MobileMe came out an Update ran that changed all the .Mac references to MobileMe and added the option to many apps including iChat.
Trial MobileMe accounts do not work after the 60 day trial. (The trials need a active Credit card registered and also Active Cancellation).
In Tiger there was no MobileMe update hence the work around for adding @me.name as AIM names.
The Get an iChat Account Button used to lead to @Mac.com for a registration as a trial when Adding an Account/Screen name to the iChat > Prefs > Accounts
In Leopard this button, more recently, this has led here
So now @mac.com names are being used as iChat Screen Names.
The downside is that you get stuck with the password you first set up.

IChat not connecting to AIM account

I can seldomly ever connect to AIM on my iChat app.
Im using te standard AIM 4.7 from AOL.com, but iChat cant connect.

Hi
Apart from Rj's advice.... Do you use the same AIM screen on both apps ?
Have you set the Multiple Logins option in iChat > Preferences > Accounts section
Select the AIM account in question and then the Account info tab. This has a check box at the top of the pane to Enable Mulitple Logins.
You have to be logged out of AIM first (all apps)

IChat wont connect with AIM

I've literally been through this entire forum looking for a solution but I have found none. I keep getting the timed out message from iChat saying it cannot connect to AIM. I have tried that changing the port to 443 thing. I've tried deleting that com.apple.iChatAIM.whatever thing, and I even tried finding my DNS server numbers and re-putting them into my system to change it. But all to no avail. This is truly astonishing and I'd really like to know how I'm going to fix this because I'm basically at wits end.

If you have tried everything on the forum I would suggest to have a look at your subscription with your ISP. If your camera works with Photo Booth it'll probably work with iChat. Sounds like a quick check with a new user account could be telling you more. Start here:
http://www.aim.com/
With your new screen name:
Choose iChat>preferences, click accounts
Click "+" in the account window and select AIM
Register your new AIM account and see if it works in iChat.

Ichat Not connecting to AIM.

Im having a problem with Ichat. Since this afternoon, I have been unable to connect to my AIM account on Ichat. It was working fine, I put an away message on and left my computer for a few hours. It was open and it went into sleep mode. When I came back, It stopped working. I tried restarting the computer, modem, wireless, everything. Nothing seems to work. And then the Ichat almost like spasms and signs on and off like 5 times until I get an error message telling me I've tried to log on too many times. All the other internet programs work but Ichat. So now I've been forced to use the actual AIM program, which everyone knows that the program is WAY outdated and extremely buggy. Can someone PLEASE tell me what is wrong. I have a Macbook Pro with Leopard.
Thank You,
Ryan

Nope it is a combo of things.
Leopard and the rush from new or retrying Mac users.
GoogleTalk has added AIM protocols (Goodness only know how many people that has added)
At this time of year AIM clear out unused Screen names to allow them to be reused.
This often causes synch problems with the AIM Servers as some people will still list those Buddies in their Buddy list.

IChat spotty connection w/ AIM

Hey I'm a recent switcher from XP and I have a new MBP. The problem is that sometimes, approx ~ 2/10 tries, iChat will establish a video link with AIM. The rest of the time it just gives an error on the AIM users side, my mother who is using vista.
What puzzles me is that it works sometimes, like I said not a lot, so its hard for me to troubleshoot what the issue is. The sad thing is we had wanted to get this working before I headed back to school. Any help would be MUCH appreciated.
EDIT: Things started going wrong after the latest 'security' update to iChat. Previous to that it was working fine for the 2 weeks I had it.

If your mother has AIM 6.5 on Vista and you are getting some success then you are ahead of the game officially.
The AIM site actually says AIM 6.5 does not do Video chats to iChat.

Unable to connect to AIM via iChat- Adium works fine...

I have been trying to get this to work for a long time, but just can't figure it out.
I am currently using Adium and everything works fine and connects, but Adium has no support for video so when I want to do a video chat, I used to just login to iChat.
Now, when I try to login to iChat, I get the "Lost connection with AIM" error.
It will sometimes connect for less then a second, then it just dies.
I have checked logs and just cant figure it out. I am not using a proxy, I know the server settings are correct, and I don't have anything on my router that could cause this- especially because it works fine with Adium...
Anyone else ever had this problem? If so- know any way to fix it?
Looking at logs, I see its doing:
Tue Oct 9 2007 00:54:11.672 PDT -Allw- local:0 -> 192.168.1.1:53 (domain) udp4 'lookupd (15310)'
Tue Oct 9 2007 00:54:11.696 PDT -Allw- 192.168.1.1:53 (domain) -> local:61846 udp4 'lookupd (15310)'
Tue Oct 9 2007 00:54:11.696 PDT -Allw- local:55479 -> 64.12.200.89:5190 (aim ) tcp4 'iChatAgent (23718)'
Tue Oct 9 2007 00:54:11.696 PDT -Allw- 127.0.0.1:61847 -> 127.0.0.1:61847 udp4 'iChatAgent (23718)'
Tue Oct 9 2007 00:54:12.182 PDT -Allw- local:55480 -> 64.12.24.129:5190 (aim ) tcp4 'iChatAgent (23718)'
So it looks like it is finding the IP and connecting to it, but its connecting to multiple IPs for AOL? I just have no idea...

Hi
Try logging on to AIM on port 443 rather than port 5190.
Go to IChat in the menu bar > Preferences > Accounts.
Log out of AIM and then use the Server Settings tab
Set the port to 443.
Log back in again.
Tony

Every time I try to sign on it says that ichat lost the connection to the AIM account and the server connection was unexpectedly lost. How can I fix this?

Note For others.
For the Port Changes (or server names in some cases) you have to be logged out to make changes on the Server Settings pane.
