Issue
On-Premises Contrast Server won't start after changing port to 80 or 443 on Linux system.
Cause
Ports below 1024 on Linux systems are considered privileged / system ports.
Resolution
Possible workarounds are:
- Run the server as root (but this is generally not recommended, for security reasons)
- Set up a reverse proxy (nginx, haproxy or similar)
- Use port forwarding (see here for an example)
