Tested the new 3.2.0 release (free community edition as \*.deb package) on Debian 12

Previously working version: 3.1.0

Update installation - ok

Problem:

My setup (Datagerry behind nginx as reverse proxy) does not work anymore.

I get connection errors in the browser right at the start page.

The EXACT same configuration _works_ with the previous binary (version 3.1.0).

This is reproducible as when I symlink the new/old version then with the new version the problem occurs while symlinking to the older version works! (Of course I stopped and killed the old datagerry processes before switching the versions and starting the service a new)

NOTE: I had the exact same symptoms previously during the transition from 2.2 to 3.0 until it was finally fixed in 3.1

Hi @cmdbeval1 ,

in version 3.2 we added the configuration file “app-config.json”.  
Please adjust the values in this file to your needs.

You will find the documentation for this here:
