Symptoms

The Bitbucket Server logo displays an incorrect URL while all other links are correct.

Cause

A. Your server.xml is not properly configured  (this issue usually occurs after upgrading Bitbucket Server version 4.x). After upgrading Bitbucket Server you need to manually reapply any previous customization in your previous server.xml to your new server.xml.

B. Your proxy is not properly configured. 

Resolution

A. Your server.xml needs to be configured as described on the step "Update any custom configurations" of the Bitbucket Server upgrade guide document. Usually the parameters redirectPort , scheme , proxyName and proxyPort are missing from your new server.xml installation and a diff between the two server.xml files (new against old installation) should show that. For specific instructions on how your server.xml should be configured, please refer to the Proxy and secure Bitbucket which will contain your specific set up. Note that adding these parameters to server.xml requires a restart on your instance before it takes effect.

B. Bitbucket Server uses the 'Host' HTTP header which is being sent via your proxy. From the discussion on this Answers post successfully updating the URL required this additional directive in the nginx configuration file (i.e. nginx.conf):

proxy_set_header Host $host;

For example, nginx.conf:

server {
    listen          443;
    server_name     mycompany.com;
     
    ssl                     on;
    ssl_certificate         <path/to/your/certificate>;
    ssl_certificate_key     <path/to/your/certificate/key>;
    ssl_session_timeout     5m;
    ssl_protocols           TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers             HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers   on;
     
    # Optional optimisation - please refer to http://nginx.org/en/docs/http/configuring_https_servers.html
    # ssl_session_cache   shared:SSL:10m;
    location /bitbucket {
        proxy_pass          http://localhost:7990/bitbucket;
        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;
        proxy_set_header    Host $host;
        proxy_redirect      off;
    }
}
