Email not working

After taking the plunge and moving a lot of my accounts over to my /e/mail, I’ve been very pleased with the whole ecloud experience… until today.

I can log in to the ecloud, and view my files/contacts/calendar etc. no problem.
But when I click the email tab I am met with another login screen. When I try to log into my account I get a message reading

Can’t connect to server

I cannot view my email, not from 2 computers (on different networks) nor from my phone on mobile data.
My phone email client (FairMail) sent me a notification stating that it can’t reach my email server as well.

Does anyone have any idea what could cause this?
Thanks in advance.
