Alexa not signing in

My Alexa integration says that it needs to be reconfigured. When I try and reconfigure it I confirm all the information on the configuration page. I then verify the 2fa code and am brought to the sign in page. When I sign in I then get a 500 internal server error " Server got itself in trouble"

Any ideas how to reconfigure and sign back in?

Same problem here, I tried thousands of times

It is so annoying. Nothing seems to fix it
