Nostalrius Begins - Quality wow vanilla realm (1.12)

Does anyone have the issue where your chat seems to stop working completely? My /say and /1 General Chat doesn't work periodically and it's really frustrating. Sometimes it'll work for 1 or 2 lines, then stop working for 10 minutes regardless of if I relog or not. Whispers work fine, but any type of public chat does not. It seems completely random and I can't chat to party or trade..

I relog, exit, reboot, leave channel and rejoin, etc. nothing seems to remedy this problem. Is it a server side chat issue that I'm not aware of?

I do not seem to have this issue, but, that doesn't mean it isn't happening, do you have any addons installed that may be interfering with it?

I did have trouble with /1 chat once before but logging out was the solution for that.

I had this issue all the time. I'm resolving it by running a macro:
/leave General
/leave LookingForGroup
...
/join General
/join LookingForGroup
...
