A friend told me about owncube, so i wanted to create an account there from nextcloud-providers page.
Unfortunately, the registration just produces an error at the moment.
Could be, it is due to non-reachable terms of service? Seems like they changed their url from agb_en.php to legal_en.php
I tested it also and it also not worked. I think you need another provider or send an e-mail.
Perhaps you can use another provider. Do you need a german provider?
@ Nextcloud GmbH: please correct the list of providers, thanks
