If you authelia setup in a docker container behind an NGINx proxy on Server 1.
If you successfully use set $upstream_authelia http://[host_ip]:9091/api/verify; to use authelia to protect endpoints on Server 1.
However, say on Server 2 if you have other endpoints and want to protect. If you use
set $upstream_authelia https://authelia.mydomain.com/api/verify;
the redirect fails and you get a 500 error.
you can use below authelia NPM config fles on remote endpoints securely.
On the server hosting Authelia :
Head over to advanced and paste the following :
location /api/verify {
set $upstream_authelia http://authelia:9091;
proxy_pass $upstream_authelia;
}
location / {
set $upstream_authelia http://authelia:9091;
