Hi,
I have searched around and tried tons of different tips and trix without any success. I have an Nginx reverse proxy installed which are working fine. All my urls are working as they should including redirect to different services on the same server. (That is why I need the reverse proxy)

However I have one issue. My unifi controller send out emails to my customers when an AP or other equipment goes down with a link to unifi.xx.se:8443 and when that is used my letsencrypt certificate will not be in use, but it is in use for both http://unifi.xx.se and https://unifi.xx.se.

I have this configuration in my /etc/nginx/sites-enabled/xx.conf


server {
listen 80;
server_name unifi.xx.se;
return 301 https://$host$request_uri;
}

# For ssl
server {
ssl on;

location ~ /.well-known {

}

location / {

}
}


Is it possible to change the request before sending it further from unifi.xx.se:8443 to unifi.xx.se?
