Teslamate new install not working on unraid?

[mbc0]

Hi,
I have tried installing Teslamate on 2 different unraid servers and have the same problem on both so I must be doing something wrong?
I installed the teslamate template teslamate/teslamate:latest
installed postgresql17
installed mosquitto

everything is running but It seems Teslamate cannot see postgres? I tried seeking support in the Simon's Unraid Templates support section on discord but it doesn't look like anyone is supporting that discord?

If anyone can help I would really appreciate it!
