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

a=candidate:3 1 TCP-PASS 1768161535 1.2.3.4 50006 typ srflx raddr 192.168.1.157 rport 50006

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

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

hojthojt commented

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

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

xhaakon commented

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

xhaakon commented

@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.

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