Web UI not working after trying to access the hostname url.
SUMMARY
So , I have installed AWX and it is connected to an external DB which also on a RHEL 8 VM.
After installing the awx , I am trying to connect to the UI but it showing as the awx box refused to connect.
I am able to telnet from my host vm to the database server but somehow awx install is not able to talk to DB
Admittedly, there are differences in the installation (e.g. CentOS 8 vs RHEL 8, External Postgres vs PG Container), however, the thread discusses the fact that there are communication issues between awx_task and Postgres.
Take a look at the firewall settings for the AWX Docker network (awxcompose_default) by default.
I remember using an external PG DB on a different RHEL server. I also remember allowing incoming connection in the Db config files when i was able to see connection errors to db.
Try validating if the following files are configured to accept incoming connections:
