this is my original issue link in github: https://github.com/coracle-social/zooid/issues/13
i showed the error and the line that cause it in the above link
in summary i have a nginx running on non-default port(8443) and the auth request fails because the public relay url that zooid thinks it has does not contain port i cannot include port in host in zooid config file

Thanks for re-opening, I believe this is a configuration error, the host should include the port the client is connecting on (8443 if I understand correctly). Why aren't you able to set the port in the config file?

i tried "zooid.mydomain.com:8443" in zooid configuration but then zooid sends 404 for everything.
my guess is that i does that because:
client request(from x to zooid.mydomain.com:8443) -> nginx -> sets Hosts header to "zooid.mydomain.com" and sends it to zooid -> zooid -> compares request Hosts header with host included in configuration file which means "zooid.mydomain.com" != "zooid.mydomain.com:8443" -> so returns 404

now i tried doing proxy_set_header Host $host:$server_port; instead of proxy_set_header Host $host; in nginx and still same issue (edit: now i understand why this failed too. i had using a nginx stream block which redirects requests to nginx http block. in my situation this makes $server_port wrong value and it's not equal to 8443)

Wowwww. replacing proxy_set_header Host $host; with proxy_set_header Host $http_host; in nginx and using host with port in zooid configuration seems worked!!!
thank you very much

can you place add a notice in README to notify peaple that they should include port in host zooid configution if they are not using 443?

and using wrong proxy_set_header Host $host; is very common. it's nice to have a notice for that too.
i found that in this link: https://serverfault.com/questions/363159/nginx-proxy-pass-redirects-ignore-port#407983
