Comment (by cohosh):
More information:
I got it to go into an infinite loop again. This occurred when a client
outside my network attempted to connect through my proxy. The debug logs
show:
{{{
Snowflake: Broker: Successfully replied with answer. snowflake.js:1194:13
XML Parsing Error: no element found
Location: https://snowflake-broker.bamsoftware.com/answer
Snowflake: At client capacity.
ICE failed, add a STUN server and see about:webrtc for more details
Snowflake: At client capacity.
}}}
And then the proxy stops polling and remains at capacity. It looks like
the answer is received and so the proxypair is set to active, but the
datachannel is never opened. When going to `about:webrtc` to look at my
local candidates I see only
{{{
a=candidate:0 1 UDP 2122252543 192.168.1.2 58106 typ host
a=candidate:1 1 TCP 2105524479 192.168.1.2 9 typ host tcptype active
}}}
which would work for a local client but not a remote one. So it seems STUN
isn't giving non-local candidates. So there are two things that need
fixing:
- We should make set a timeout on datachannels opening to avoid infinite
loops
- We should figure out what's going wrong with STUN
