nginx leaks my hidden service port number

Question

I have my .onion service running:

http://oeptyn6jtusgda63.onion/

When i try to open wrong link, my TorBrowser shows me an error like this:

Firefox can’t establish a connection to the server at oeptyn6jtusgda63.onion:7541.

Is there some way i can prevent nginx to leak my server port number?

I have learned myself, that nginx first send redirection (http code 301) that leaks my port number. Is there some way i can disable it?

UPD :

This happens when i try to access some directory, like this:

http://oeptyn6jtusgda63.onion/zip

Answer 1

I fixed it myself. I just added this directive to nginx.conf :

port_in_redirect off;

This directive briefly described in nginx doc: https://nginx.org/en/docs/http/ngx_http_core_module.html#port_in_redirect
