Bot gets stuck half-offline

[cmsj]

I seem to have to restart irccat every few days, when logs are getting this error every couple of minutes:

2020/06/08 22:24:12 Error, disconnected: SASL setup timed out. Does the server support SASL?
2020/06/08 22:24:13 Connected to irc.freenode.net:6697 (204.225.96.251:6697)

When it's in this state, it's still receiving events from GitHub, but is unable to relay them to IRC.

I think this is probably the same issue as #21? I haven't quite pinned it down yet, but it doesn't happen that often for me.

Possibly, although I haven’t noticed that same error message.

I was looking at go-ircevent as the possible culprit and found this commit: cpatulea/foubot2@49e7b95 which didn’t make me feel good about being able to fix this quickly!

We're still running into this, even after disabling autoreconnect [edit] and adding a manual reconnect loop using irccon.Reconnect() (FOULAB/foubot2@c5e90db):

This time a human noticed a problem and rebooted it.

This happened again for us, so there's definitely a bug. I'll take another stab at a workaround next week.
