The duplicate TCP-PASS candidates with foundation 3 shouldn't be there:

The IP denoted by 1.2.3.4 is the pubic IP address of user's internet connection.

Note the candidate duplication happens also when a different relay is used.

Unfortunately, libnice debug logging is insufficient. We should dump connection check list after the gathering is finished too.

I get the same error when I try to accept a shared screen... but today I get one more line in the error message:

Error occurred

Unable to establish a call 488 Not Acceptable Here

Previous hop federated peer did not report diagnostic information

xhaakon commented 8 years ago

@overisberg error 488 is very generic and can mean a lot of things. If possible, please provide your Pidgin logs.

hojthojt commented 8 years ago

Hi, I have had this problem a few times now and I have the feeling that it has something to do with when I move my computer between different network connections (wired, wifi, different wifi access points). But this is just a "hunch". Restarting Pidgin is not enough since today I restarted Pidgin in debug mode and still got the error. I have the pidgin.log from: GST_DEBUG=3 G_MESSAGES_DEBUG=all NICE_DEBUG=all,libnice-nice-verbose pidgin --debug |& tee ~/pidgin.log Mail me if you want it. I attached the package versions I was running. versions.txt

xhaakon commented 8 years ago

@hojthojt If you don't want to post the log publicly, please send it to the mail in my profile.

xhaakon commented 8 years ago

@hojthojt Your issue is unrelated to this one. I've opened a new ticket for it: #83.

xhaakon commented 8 years ago

@overisberg Your problem is likely the same as in #83, which was affecting everybody with 14.04. Please update pidgin-sipe if you haven't yet.

@xnandersson This needs a check for reproducibility with recent libnice package.

xhaakon commented 8 years ago

Not reproduced with recent libnice within 14 days. Considered as fixed.
