No, there isn't. This error message is in 95% of cases (low estimate) an intermittend problem that seems to have their cause somewhere in the net infrastructure between you and the server. It doesn't effect everyone or even most players.
It usually goes away after some hours (which is frustrating), but normally without the player doing anything (though testing on another device or another browser never hurts). In the very few remaining cases it really is the server that has a problem, but that usually means a high volume of error reports here and on discord.
