High Performance Backend working/not working?

[SimonWolf]

First of all thank you very much for your tutorial and your help now!

I do understand the connections, thanks for explaining that.

To me it looks like

• NC application talks to the notify_push
  working
• notify_push talks to NC application
  working
• client talks to NC application
  working
• client talks to notify_push
  not working

Now my question is: Why does my browser even want to connect to dev-nextcloud-notify_push:7867 ?
Or in other words, how can I tell the client to connect to my cloud.server.de domain (to reach dev-nextcloud-notify_push and nexcloud_app)?

@wwe

#display ip address of the user
https://${NEXTCLOUD_FQDN}/index.php/apps/notify_push/test/remote
#JSON with content "null"
https://${NEXTCLOUD_FQDN}/index.php/apps/notify_push/test/version
#some number (cookie id)
https://${NEXTCLOUD_FQDN}/index.php/apps/notify_push/test/cookie

These tests work! But that doesn’t mean that my Traefik configuration for dev-nextcloud-notify_push works right?
Is there a way I can test if that’s working correctly?

Or do you have any other Idea what could be the problem with my setup?
