Any ideas?

Maybe start looking through Setting up Files (High Performance Backend) double check installation steps and the references.

I remember redis is important for notify_push and the error

sounds like something is wrong with it. which doesn’t really match to




  'trusted_proxies' =>
  array (
    0 => '',




  'trusted_proxies' =>
  array (
    0 => '',

Errors are not yet logged in apache2 and notify_push
I’ll write after a while whether the problem is finally resolved

Error occurs while restarting redis-server

[notify_push::connection] src/ Invalid credentials

Today these errors appeared again in the Apache log (nothing was changed) :frowning:

Added the following variable to the Apache configuration (for apache2 version 2.4.52)

# Add
SetEnv proxy-nohalfclose
ProxyPass /push/ws ws://
ProxyPass /push/
ProxyPassReverse /push/
