OS X 10.10.2 Your connection failed because the communication device is unavailable. Make sure it's connected to your computerunication device is unavailable. Make sure it's connected to your computer and try reconnecting ad try reconnecting

There is precious little information concerning this warning dialog. If I am disconnected from any network; wifi, Bluetooth, Thunderbolt Ethernet, doesn't matter, I get this error in a pop-up dialog. "Your connection failed because the communication device is unavailable. Make sure it's connected to your computer and try reconnecting" Creating a new Location under System Preferences / Network does not solve the problem. 1. What is asking to be connected? 2. How do I stop this? Running Yosemite 10.10.2 on a MBP 13"

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Hi there
Do you happen to use a USB modem or something like that? This could be the cause.
You could try creating a new network location to see if that fixes it (if not you can just reverse it)
1. Go to  Menu -> System Preferences
2. Then go to Network on the 3rd row
3. Make sure the padlock is unlocked (bottom left) with your admin password
4. Choose 'Automatic' next to 'Location' at the top.
5. Choose 'Edit Locations'
6. Then click the + button, and create a new one called home/test/somethingorother
7. Click Done -> Save and wait a few seconds
8. You may have to reconnect to your Wi Fi network etc.
If you have a USB modem, the above steps will most likely remove its config from the Network preferences. As I said, its reversable (just change location back to automatic)
Have fun

Hi IG viper,
Placing your iPod into recovery mode should allow you to successfully restore the device.
You might see these error messages if any of these are true:
Your device has a beta version of iOS.
You're trying to install an earlier version of iOS (downgrading).
Your device has unauthorized modifications to iOS, also called "jailbreaking."
Use recovery mode to restore your device to the latest version of iOS.

Oracle8i ora-12545: connect failed because target or object does not exist

I am trying to get a Oracle8i database working on a Windows 2000

I think ur not configured or installed directory server..
Do this then it will work fine.

Get ORA-12545: Connect failed because target host or object does not exist

Hi all,
My database is in RAC on a RHEL 5 and oracle 10.2.0.4 release, when i connect from client at the first time it's connected and after exit and connect again it gives the error ORA-12545: Connect failed because target host or object does not exist. and trying to tnsping i can reach the server and connect again it's connected and after disconnect and reconnect it gives the same error.
Here is my tnsnames from windows client:

An HNAP call to the device failed because the HTTP connection was broken - EA3500

OK - thanks in advance for your help -
I have a linksys Linksys WMP300 and am able to connect to the EA3500 (shows connected at 270 Mbps) Excellent Connecttion but I can't access the internet or any of the other computers on my network. The stupid thing is that I can connect to my neighbor's unsecured network which is also a linksys router.
All of the other computers on the network connected just fine - my son has a laptop running windows Vista, we have a family computer using Vista, my wife's laptop is Windows 7 (we just had a guest that connected just fine).
Here's the error code I get - any help would be appreciated!
Error code: 82BD0304
Error description: An HNAP call to the device failed because the HTTP connection was broken.
Model name: unknown
Model number: EA3500

Thank you for the reply -
Router is assigning IP address automatically. Although I have been using a static IP address in the past, this is no longer the case.
The WMP300 is on an Windows XP, SP3 PC.
Since running into this issue, I have not only disabled all security (to make sure that firewalls and/or virus software was causing problems) I completely uninstalled my McAfee. I have disabled Windows Firewall also. "Flying Naked" as it were.
I am surprised that Cisco has no solution - others are also having this problem.
It MUST be the router - I am able to connect to my neighbor's router, able to connect to my old Linksys WRT150N. Anyone else have thoughts?
This is frustrating.

Hi Guys,
Thank you both for your responses, my findings are as follows:
1. HOST=X.X.COM, ensure host is reachable : PING works and host(s) are reachable.
2. In RAC Env, ensure TNS Name is correctly spelled, spelling fine, i can connect with the tns name (is TNS name same as SERVICE_NAME?) by: sqlplus 'user/user@racenv'; but my efforts still will not allow me to use:
sqlplus 'user/user' it tells me that the host or object is does not exist, does this refer to the actual physical machine or the service name, or the instance name?
All host entries in my tnsnames.ora file refer to the vip addresses of both servers holding the rac installation, and both are resolved just fine, testing with ping; any other way to test this?
tnsnames file contains CONNECTION strings in the following order (does the listener entry need to be in the file? on the machine that i am trying to connect from?):
LISTENER_ORCLTELE =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.9)(PORT = 1521))
ORCLTELE =
(DESCRIPTION =
(ADDRESS_LIST =

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))
(CONNECT_DATA =

I tried removing all entries but the entry for MSRAC, but still no joy:
MSRAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.12)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.13)(PORT = 1521))

A connection attempt failed because the connected party did not properly respond after a period of time

Prior to the Increase Capacity for Outbound Network Calls update, my Azure websites running in
Standard mode experienced occasional connection attempt failed errors. Since this update the errors stopped but starting on 12/30/14, these errors started up again on both
South Central and East regions:
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond [IP]:80"
It occurs when attempting to consume an external web service over HTTP. This issue is not reproducible on our local environments nor did it occur with our previous shared hosting provider.
On Azure, the same web service call can result in this error or will return a response successfully.
There doesn't appear to be any pattern as to why the same call would work one time but not another.
How can this be resolved again? Any feedback is appreciated. Thanks.

Hi,
Please have a look at this article:
http://blogs.msdn.com/b/narahari/archive/2011/12/21/azure-a-connection-attempt-failed-because-the-connected-party-did-not-properly-respond-after-a-period-of-time-or-established-connection-failed-because-connected-host-has-failed-to-respond-x-x-x-x-x-quot.aspx,
it gives us several ways to solve this issue, hope this helps.

suggestions
ok VIPs
can client access the server(TNSPING utility).
or simply ping the server.
if client able to communicate server then check HOSTNAME in listener.ora
is represting correctly your Host.
is hostname map with virtual ip in host file of Operating System if not using DNS.
check ur hostname with command hostname.

Connection for Source failed because the environment is not trusted

Good day all,
This is the second time I come across this error on two different forms.
This happens whenever I have a form connected to my database(SQL) and configured my ODBC.
My form is Reader Extended, when I load it outside LC Designer I get this error : "Connection for Source failed because the environment is not trusted".
I have searched for solution, one that I saw says one must change bindings from None to Normal, I've done that and didnt solve my problem.
Can someone please assist me.
Regards,
Ace

Check the two below links and see if they can be of any helpful to resolve your issue.
In this thread Paul is asking to change the DSN setting.
"If you set up your DSN as a system DSN instead of a user DSN then that message shoudl disappear."
http://forums.adobe.com/message/2873482
In the below blog, Steve is mentioning to clone the connection to get rid of the issue.
You should be able to get around this by changing this line:
var oDB = xfa.sourceSet.nodes.item(nIndex);
to this:
var oDB = xfa.sourceSet.nodes.item(nIndex).clone(1);
