Homer shows "You're Offline Friend" after 30 seconds

[rarick]

My setup

• traefik as a reverse proxy & domain controller
• thomseddon/traefik-forward-auth as my forward auth provider
• auth0 as my oauth provider
  • All my domains and wildcards are entered in auth0 for CORS/origins

The issue

Homer is behind the authorization proxies. I am seeing "You're offline friend" after 30 seconds on homer. I'm not offline, and I can always reload the page without issue (hard reload as well). I see that the request is to mydomain.com?t=<unix timestamp>. This is receiving a 500 error, but I don't know where this response is coming from.

I see the request callstack starts with checkOffline.

Any ideas why this is happening?

Hi @rarick

Hum, that's weird. The connectivity check request (which can be disabled) is an HEAD request, maybe traefik block this kind of request? Can you tell if the request hit the container or not? Is there a message associated with the 500 error ? Can you also check the container logs?

I have a nearly identical issue.

Setup:

• traefik2
• thomseddon/traefik-forward-auth
• Google oauth

I also get the "offline friend" message after 30 seconds, which is solved by refreshing. You mentioned the connectivity check could be disabled. How do you do this?

EDIT: my bad for not RTFD. I totally missed that line of the example config. Disabling connectivity check stopped the problem happening for me.

Same problem here

I have the same issue, but instead of traefik I use the Explicit Proxy build into a FortiGate firewall. When I check the developer tools in my browser I see that a request is made to the following URL: http://dashboard.int.mydomain.be//index.html?t=1660243712402

So with 2 // instead of 1, this request gives back a 504 gateway timeout.

Thanks for the feedback, @zhenry9. Disabling the connectivity checker will workaround this issue. @rarick @Fratt @vincentvriends Have you tried that?

That being said, the connectivity checker should work, it just periodically send a request to the server and execpt either an http response code in the 200-299 range OR a redirection (to handle auth proxy redirection, il this case the whole page reload and follow the redirection). If you don't need that, you should disable it anyway.

Hi, where exactly do you find this connectivity check option? my config.yml only has things that should or hould not appear on the html page and theme related stuff... Thanks
