I have actually had the same issue in the past, eventually it just went away but for a little bit I had to use a VPN to log onto the server. I donβt believe it is something we can fix on our side.
Iβve found a slight solution for it. Iβve noticed that about 1/10 times I try to connect things go well. Iβve reliably managed to log in after logging in and out several times. Not ideal, but after about five minutes of trying I can usually log in.
