It’s happening to both repl and firewalled repl for me

i’ve raised it as a bug here but unfortunately it has not been resolved and i’ve even managed to raise it as a support ticket but no reply at all, this was 6 weeks ago.

Yeah, repl has become quite incompetent now since the newest changes.

I guess they want their website to die and get replaced :man_shrugging:
