Today I can not connect to Disroot via Nextcloud 2.5 client on Windows and Linux. The status says "Nextcloud: Disconnected from email@example.com". I also tried logout/login but still am not able to connect even if the status of your services are green (except Nextcloud Circles - I'm not using that). But the android app is working as expected - I can upload and download files withour problems. Also login via web services also works without problem.
And Nextcloud client is working OK with my local server.
Is there something else I could check regarding this issue or is there a problem on your side?
