When I try logging into Rohan, I used to get "create device failure" but I managed to fix that, but now when I get to the login screen and I enter my information I get "HTTP_STATUS_SERVER_ERROR" and "Login failed"

I have already submitted some tickets and followed all the suggestions, restarted modem, restarted computer, reinstalled Rohan, ran as an administrator, ran with compatibility settings, (they said weak internet or wi-fi, but I'm using an ethernet cable and I have highspeed internet) so I don't know what else to do.

Any help will be appreciated.
