Error message registering with any email address


I can’t even register in Nextcloud because I receive an error message with every email address I type. I’ve tried with yahoo, hotmail, gmail and everytime I get “Error: Something happened”.

Thank you for any advise

Can you send more details screenshots, serverlog, etc

Dear Nihe, I’ve just tryed with a account and everything went right. Thanks anyway for your kind and quick attention.

What do you mean by “in Nextcloud”? We need more information about your server, installation, etc.

That doesn’t seem right. Do you host a Nextcloud yourself? Do you use the Register app?
