Keep receiving Hmm...something seems to have gone wrong

Just keep receiving the same error message no matter what I type. Started a few days ago and there is no change with the settings. Clearing cache and chat history doesn’t help. I have check my second account and it works well. Also, the error happens across different platforms since my ios is also returning the same error. Looks like this error message is targeting accounts rather than Internet connections or other issues.

Anyone has some idea what is going on?
