I am having same issue as on my few months old post
https://forums.nina.chat/thread-82.html unable to send or recieve messages.
I am getting error from sending failed and friends (who has no issue send or recieve messages) cannot reach me.
Like mentioned on previous post I created new account to new email to fix it but feels same old bug is back. I tried disable firewall, filters and others and reinstalled and verified client is migrated properly without luck. Here is my log from messenger to anyone who understand errors better. Some of those looks same when glitched last time so hopefully it is not account issue again since I am out of emails.
