It's just the usual 502 errors.

I also get these from Voice connections too.

Press any key to continue . . .

Also if only d.py would allow you to disable seeing the 502 errors.
I think on the keep alive handler for vws to try and see if it is closed and if so reopen the main ws. So this hopefully gets fixed.

The image is fixed above if you add a check for 502's and log.debug the info from it in _rate_limit_helper. @cookkkie
