Unable to change port number in Bitbucket - bitbucket

Question

My Bitbucket instance is running in an Ubuntu server.
The initial installation was done by following the wizard and in that moment it was set the default port 7990.
Now I would like to change it to use the port 443, so as per the official documentation it can be easily done by changing the value server.port in the shared/bitbucket.properties file.
However, after that change, the server is not even listening in the new configured port.
Bitbucket is started as root user.
Why is bitbucket not taking into account the port modification?

Answer 1

Fixed after configuring a Nginx server which will do relay between port 7990 and 443.
Config bitbucket:
server.port=7990
server.proxy-name=******************
server.proxy-port=443
server.scheme=https
jdbc.url=jdbc\:postgresql\://localhost\:5432/bitbucket
jdbc.driver=org.postgresql.Driver
jdbc.user=******************
jdbc.password=*************
Config Nginx:
server {
location / {
proxy_pass http://localhost:7990;
proxy_redirect off;
server_tokens off;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
}
}
server {
listen 443 default ssl http2;
