Problems with notifications

Nextcloud version: 16.0.3
Operating system and version: 18.04 LTS
Apache or nginx version: nginx/1.17.2 (fpm-fcgi)
PHP version: 7.3.8

The issue you are facing:

I was faced with no notifications of Nextcloud and Nextcloud Talk work. As for mobile applications Nextcloud Talk notifications can’t work too, although there is no problem with linking. Thank you in advance and sorry for my bad English :slight_smile:
Notification is app installed.

Is this the first time you’ve seen this error?: Yes

Steps to replicate it:

  1. Tried make video call and send message in NextCloud Talk
  2. Tried to make event in calendar for my friends
  3. Tried to invite my friends into room

The output of your Nextcloud log in Admin > Logging:
Many messages like this:

"Exception: The requested uri(/GponForm/diag_Form) cannot be processed by the script '/core/templates/404.php') at /var/www/html/lib/private/AppFramework/Http/Request.php#780"

I think it hacking attacks and it doesn’t matter for my problem.
