Service not accessible

I’m trying to use the IE service for the first time. But I can neither access the service nor add a payment method. I always get a 504 error although it looks like the services are running and no maintenance is scheduled. Could this be a problem on my side or is HF infrastructure having trouble right now?

+1, the same 504 error

+2, the same 504 error.

Guys, could you please help with this issue.

It’s working again. Thanks to whom it may concern!
