Reverse proxy issue?

is there a env variable missing for reverse proxy support, on the unraid app x-forwarded-host header with value localip does not match origin header with value homarr.home.com from a forwarded Server Actions request. Aborting the action. does the template support adding a proxy_domain variable? Also to note this is with nginx proxy manager secured with Authentik

Solution:

So you added the following fields?: ``` location / {...

Can I install Homarr on a Raspberry Pi?

Okay that's intresting, I think nobody else had that problem with a reverse proxy yet, can you maybe share some more details from your setup? Probably related: https://nextjs.org/docs/app/api-reference/config/next-config-js/serverActions#allowedorigins

What else would you like? My nginx config?

Meierschlumpf•2mo ago

Yes (I only need the homarr part other services are probably not important)

this is what my npm advanced tab looks like. this setup has always worked until v1.0 fyi here is the exact log entry

`x-forwarded-host` header with value `192.168.1.50:7575` does not match `origin` header with value `homarr.home.com` from a forwarded Server Actions request. Aborting the action.
 ⨯ [Error: Invalid Server Actions request.] { digest: '4021323368' }

Thanks, I'll investigate further tomorrow

I tried to find a solution for something in that direction and I'm not quite sure if there is one. That said, can you investigate the reason why the x-forwarded-host is 192.168.1.50:7575? And with which url are you opening Homarr?

b_d0nOP•2mo ago

As far as I can tell the x-forwarded-host shouldn’t be directed toward the servers ip:port it makes 0 sense and really shouldn’t even be working, but it is? And I’m using the correct url to open my homarr, if that is what u mean? I’m not gonna share the url here

Meierschlumpf•2mo ago

But are you using the ip with port or a domain?

b_d0nOP•2mo ago

Where would I verify this? In my nginx correct? 🤦🏼‍♂️ it’s fixed I had the directives in the wrong spot.. I can’t believe it half worked tho lol 😂

Meierschlumpf•2mo ago

Okay xD, so I have to fix nothing 😂

b_d0nOP•2mo ago

For anyone that runs into this bone head mistake here is the correct nginx proxy manager advanced field: https://pastebin.com/Ju90HxTa

So you added the following fields?:

location / {
  # ...
  proxy_set_header Host $host;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
  # ...
}

location / {
  # ...
  proxy_set_header Host $host;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
