Self hosting error

Need the firewall port numbers that my survey solutions software go through. I got a support email that it could be my firewall blocking software from working. So i need the ports so that i can open it and test again.

Your firewall program should tell you specifically what it has blocked when the action was performed.
Instructions for common firewall programs are here:

Ports may vary depending on the configuration.

This error means that HQ application cannot access PostgreSQL database. Check connection string in the configuration file.
