"OOPS, something went wrong"
Is common and it IS ALWAYS THE PLAYERS CONNECTION ISSUES.
Multiple times per day you will see the message, and reporting them to 'tech support' gets the same canned answer...
Labelled as "Just the Facts" IT IS YOUR FAULT.
Their equipment is overloaded and in serious need of an upgrade, but I doubt management has a clue.
After all, "Why tell the boss you aren't qualified if you can blame the customers?"
File a complaint WITH SPECIFIC INFORMATION, come back the next day and it will magically be "SOLVED" with nothing done to correct the problems.
My suggestion is PLAY FOR FREE until the site stops breaking.
