I’d say it was flaky, for me too…
It’d time out after 10-15 seconds of trying, but if pressed again would come back OK in a second.
This time it’s different. From the github discussion it looks like the latest version of Talk is to blame. I’ll roll back to the first v.21 snapshot on one of the instances I run (on the weekend)…
EDIT:
If you install the NC+HPB VM from @enoch85 and upgrade to the latest NC21+Talk11, it works. But the same test of the TURN server on the config page fails just like coTURN server does…
EDIT-2:
Talk 11.2.2 fixes this issue…
