My Chat application has gone from not connecting 10% of the time, to not connecting 90% of the time. It was OK for the week after Fellowships were released. Perhaps there was a hotfix or some, on Monday or Tuesday. that effected the Chat application.
If I close and reopen my Chrome Browser, the chat box is blank and inputs are ignored.
If I then reload (Chrome Ctrl+F5 or clicking on the tab, which clears the buffers) I get
- connecting, for several seconds
- could not? establish connection, so fast you can barely read it
- loading chat history
So it seems that I'm getting through to the Chat server, but it's not really establishing a session.
Shutting down my AVG Firewall (Automatic Mode) seems to relieve the problem.
Which ports should we verify, to ensure that the problem isn't somehow firewall related?
I'll post a path as soon as I have one.
UPDATE:
Dropping the firewall into the interactive mode seems to have settled things down, WITHOUT manually enabling any more applications. Maybe I just needed to slap the firewall around a bit, but the more likely case is that there's a Chat pattern that the AVG automatic mode firewall doesn't like.
AVG Internet Security version 2015.9.6125
How do the automatic decisions work in AVG Firewall
So the list of acceptable applications OR the digital signature might restrict an application, BUT I would expect the firewall to ask for permission, were that the case. That's not happening, but the chat application DOES seem to work better when the firewall is in interactive mode, for some weird reason, and symptoms are symptoms.

Latency isn't likely to be the issue. I'm using a T-Mobile 4G LTE USB tethered hotspot, and speedtest.net is showing
Ping: 103 ms, Download 8.57 Mbps, Upload 5.21 Mbps From Seattle to Miami.
UPDATE2: Chat was behaving better this morning, so I switched back to Auto Mode, and it's still behaving fairly well. This is sounding more an more like an intermittent hardware failure in the Miami datacenter, so it's going to be tough to isolate.
