Could not listen to IP + Port 1111

Hi YouTrack team,

I am trying to install YouTrack 2017.2 on a server in the cloud with IIS according to this documentation [1]. During the installation process, I wanted to change the base url and the port to accordingly to 1111 (as mentioned in [1]). However, YouTrack keeps telling "Could not listen on IP and Port 1111". I can only continue with the default data which does not allow me to access the server from the web.

Like in 20. of [1] I added a binding to the IIS Manager with the following:

• type: https
• IP: Server base ip
• Port: 1111
• Hostname: my.company.com
• SSL-Certifcate: WMSVC

I even added rules for port 1111 to the windows firewall to allow traffic.

I tried to install YouTrack with various combinations of: Server base ip, 1111 and hostname, but the message "Could not listen to IP + Port 1111" remained the same (except for the default) parameters.

Any idea what went wrong?

Regards,

Thomas
