Debugging "Unknown error occurred while communicating with iT600 gateway"

[prupert]

While working on the Home Assistant integration of a Salus UGE600 gateway, I noticed that the underlying pyit600 library suddenly stopped being able to connect to the device. Because I believe that the gateway is configured correctly, and I am able to ping and HTTP the device IP address, I am looking for guidance how to further debug this issue.

I have installed pyit600 module on a VM to debug. I get the following errors:

% python main.py --host 192.168.x.25 --euid 001Exxxxxxxxxxxx --debug

Quickly gives the following output:

DEBUG:pyit600:Trying to connect to gateway at 192.168.x.25
DEBUG:pyit600:Gateway request: POST http://192.168.x.25:80/deviceid/read
{"requestAttr": "readall"}

The above exception was the direct cause of the following exception:

pyit600.exceptions.IT600CommandError: Unknown error occurred while communicating with iT600 gateway

I tried the following already:

• Changed the EUID to 000000000000: same output
• Confirmed that local WiFi mode was NOT disabled in Salus app
• Made sure the device was reachable (ping and HTTP)
• Reboot the UGE600 gateway device

The mentioned URL in the debug output responds (quickly) to a curl request:

% curl -I http://192.168.x.25:80/deviceid/read

Quickly returns the following output:

HTTP/1.1 200 OK
Keep-Alive: timeout=5, max=199

So to me it seems that the Salus UGE600 device should be reachable. I am totally clueless as to why line 957, in _make_encrypted_request raise IT600CommandError("Unknown error occurred while communicating with iT600 gateway"

Details about the UGE600 device:

• Model: Universal Gateway
• Software version: 021720240719
• Coordinator version: 20240613
