  • "The connection to the host was unexpectedly lost"

    Occasionally when I try to log in to my AIM account, I get the message, "The connection to the host was unexpectedly lost." This happens randomly and if I keep pushing it, sometimes it will let me on. It seems to be entirely at the will of the computer.

    Try the Combo Update to get to 10.4.11

  • The connection to the host was unexpectedly lost. AIM

    I am trying to connect to AIM via iChat in Mac OS X Tiger. Everytime I try to connect it shows my buddy list for about 1-2 seconds and then says, "The connection to the host was unexpectedly lost." I don't have aim connected on this computer or any other computer on the network when I try. Any help or recommendations are appreciated.
    Thanks

  • "The connection to the host was unexpectedly lost" Cannot log into AIM

    Every time I try to log into ichat, using AIM service I get this message...
    The connection to the host was unexpectedly lost.
    However, I can log onto ichat on my other mac. (macbook) And I can access AIM from AIM program on my windows computer....
    Everything in preferences is configured right...Can anyone shed some light onto this?
    thanks,
    Joel

    I have this problem, using ichat only (not using aim directly) and posted before in another thread with essentially the same name as this one. I tried all the solutions offered and none worked. BUT I did "solve" my problem. Here's how:
    Solution number 1) I connected my macbook via an ethernet connection directly to my cable modem. No other changes at all, no further problems, was able to use ALL features of ichat immediately and quite well (audio and video).
    Solution number 2) Since we have several computers at home, we must use a wireless router, a Netgear router. If I connect to the router (which then connects to the cable modem), ichat does not work, and I get the exact message as in this subject line. Going to the Netgear router settings (changing nothing on my macbook), I changed ONE thing only: I disabled the SPI firewall. Then, no problem using ichat to chat, but I still can't use audio or video features.
    Hope this helps. For me, it diagnosed the problem with using basic ichat: the SPI firewall on the router. Also, the audio/video problem is a router problem too, which I do not yet know how to fix.
    Since I am timid and fearful, I do not want to leave the SPI firewall permanently disabled.

  • Connection to the host was unexpectedly lost.

    I'm still having problems connecting to AIM using iChat. I switched to port 443, and I still get the message that the connection to the host was unexpectedly lost.

    Ok,
    Do you have individual wall sockets ?
    Do you have a router in the room ?
    IS your Wireless card set up for Interference Robustness ?
    How are the ports opened in the modem ?
    UPnP for two computers ?

    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.

  • Constantly get "The connection to the host was unexpectedly lost."

    When I try to use IChat at home on my PowerBook I get "The connection to the host was unexpectedly lost." as soon as I try to connect. This does not happen at work though. It works fine at work.
    I thought it might have something to do with the different ISP's or Router settings on my Netgear wirless router. (At home I connect via ethernet cable.) However it WILL work at home about 5% of the time.
    ANy Ideas to troubleshoot?

    Hi Scuba Dan,
    Check that Systrem Preferences > Quicktime > Streaming tab has the drop set to your Download speed.
    http://www.ralphjohnsuk.dsl.pipex.com/page4.html#_quicktime
    Also check iChat > Preferences > Video Section Bandwidth drop down is set to NONE.
    http://www.ralphjohnsuk.dsl.pipex.com/page4.html#_bandwidth
    These two will cap iChat if not set properly.
    As Defcom says if these settings are correct you may have a modem that is having trouble wiith forwarding port 5190 on both TCP and UDP protocols.
    Changing the setting he mentions drops the login below any Port Forwarding and NAT involvement on your modem and router.
    Having said that avoiding NAT and Port forwarding by using UPnP is another way around this. Most Netgears have UPnP enabled as default. You don't need Port Forwarding ANd UPnP. Disable the Port Forwarding settings by Unchecking them.
    For others,
    Zyxel devices are prone to needing port 443, as are newer devices that want protocols to be set when Port Forwarding.

  • Netgear + "The connection to the host was unexpectedly lost"

    I have an 802.11g Netgear router. I just got it, previously I had the exact same router, but 1 "version" behind.. aka it was gray and this one is white, but everything else SEEMS identical.
    Everytime I try to connect to iChat now, I get the message:
    "Lost connection with AIM
    The connection to the host was unexpectedly lost."
    My buddy list starts to come up, that message appears, the buddy list closes, and I'm screwed.
    I am set to the DMZ. I am using port 5190, but 5191 and other ports work.. but I cannot use audio or video chatting. My client shows up as "not capable" of audio or video (MBP so I'm capable of both, and did both before this new router).
    Help is appreciated, and I will gladly hand out cookies to anyone who can help.

    Hi
    Try this log on to AIM on port 443 rather than port 5190.
    Go to IChat > Preferences > Accounts.

  • Connection to host was unexpectedly lost.

    IT keeps saying that every time I try logging into ichat...and even if I get passed that, my buddy list won't show up. This even happens with adium.
    Any ideas??

    Hi
    First 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.

  • HT1766 can i back up my ipad if the host computer has lost every thing?

    Can I back up my ipad if the host computer has lost its operating system and the was re-instald?

    Yes, this would be like syncing to a new computer. So, some precautions are required or you might lose what's currently on the iPad.
    iTunes will only let you sync to one library at a time, if you get this warning message, follow this:

    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.

  • AIM - connection with host unexpectedly lost

    When I am using my school's wireless internet, I can log onto iChat for about a minute, and then it logs off and says "Lost Connection with AIM. The connection with the host was unexpectedly lost."
    If I stay on the iChat window it stays logged on, but if I bring another application to the front of the screen it eventually logs off.
    I also cannot use video chat.
    I found a similar thread that said to use port 443, which I am currently using.
    It does the same thing even if I am logged in to my .mac account. However, Adium works and everything works fine when I am at home or somewhere else. As far as I know, my proxy information for my school's wireless is correctly entered in.

    Hi,
    Welcome to the  Discussion Pages
    iChat is very sensitive to Proxies.
    In fact I would say it does not like them at all based on the posts in these forums. Many people report they can not get it to work with a proxy whether it is listed in the iChat > Preferences > Accounts > Server Settings or in the System Preferences > Network.
    I don not use Proxies and still find at some points iChat does not seem to be able to stay logged in.
    I never use another client long enough to provide a comparison.
    iChat gets constant feedback from the AIM servers to keep the Buddy List updated. More so than a Minute check setting by Mail - so I can not see it is any time-out limit on the proxy.
    Isn't iChat using port 1080 for the Proxy ? (or whatever your Proxy uses )

  • Connection to AIM unexpectedly lost

    Very often when I am not using iChat, my buddy list will all of a sudden switch to "Disconnected" and I will get a message saying "The connection to the host was unexpectedly lost." iChat used to work just fine! What can I do to get it back to the way it was?

  • The Connection has been lost by the host--AIM, iChat

    Hi. Every time I try to log on to AIM or iChat, it goes through the sequence of signing on, but then I get "The Connection has been lost by the host". Now, I would think it would be my connection, being on a college campus and all, but I have no issues surfing the web and checking my e-mail via entourage. My roommates and everyone on my floor have no issues, but then again, none of them are using a Mac.
    It worked this whole week and then yesterday it decided to crap out on me. I've restarted, turned off the computer, went back to it...nothing.
    I have MacBook using OS X, I have the latest version of AIM and iChat, and I'm using ethernet right now.
    --I've tried changing the ports in both programs...no luck.
    and my college network doesn't offer support for any IM program, no matter how hard you beg them.
