Comfoconnect not connecting - TCP Reset from server

[Brewery-GIT]

Hello;

Thanks for all this work on this nice integration. I just got my comfoconnect lan c. I installed it and was able to connect to it from the Android App. When I want to use this integration, it fails on the first step ->

Enter a ComfoConnect LAN C bridge hostname or IP address below. Then it just keeps searching and searching.

When I sniff the connections, I constantly see "TCP RESET FROM SERVER" So it seems the Comfoconnect LAN C won't let the integration connect.

Current setup:

LAN C IP: 10.10.40.19 HA IP: 10.10.80.254

Doesn't make a difference if I put the LAN C in the same network.(so with IP 10.10.80.19)

I also tried with the integrated addon as well, by adding it to the configuration.yaml file, but same issue:

2023-02-04 10:56:19.761 WARNING (MainThread) [homeassistant.bootstrap] Waiting on integrations to complete setup: comfoconnect 2023-02-04 10:57:19.832 WARNING (MainThread) [homeassistant.bootstrap] Waiting on integrations to complete setup: comfoconnect

Info:

Home Assistant 2023.2.1 Supervisor 2023.01.1 Operating System 9.5

Latest Addon.

Android App: Everything is green in "connection status" Gateway version: U1.2.6 Android App Version: v1.7.0

I already factory reseted the LAN C unit, but no luck. Perhaps you could point me in the direction where to look further? Not sure if this is related to the addon. Thanks in advance.

I have the same issue. When I try to connect to my zehnder comfo lan C it just keeps searching. It does auto discover the bridge but I dont get any further then that.

You probably also get tcp resets...I acquired the installer password to see if it makes a difference but no luck.

I also tried fully disassociating the lan c from the app, but issue remains. For now I gave up, not much more I can try.

Let me know if logs or more info are needed

I have no idea what could be wrong here, but it looks like a networking issue.

You could try enabling debug logging on the component. You can do that from the integration overview UI on Home Assistant itself.

Try restarting Home Assistant so it can try to connect. You can then get the logs from the homeassistant.log file, or probably also trough the UI somewhere.

As the integration couldn't be setup correctly, I don't have access to that menu :-(

[michaelarnauts]

You can also enable logging trough to the configuration.yaml. Can't give you the exact config right now, but I hope Google or the HASS forums can help you find it.

Apologies for delay in reply. I was able to get some further output. Now it just says: unknown error occured.

In the logs:

Do you still have this issue? I'm not sure what could prevent the connection to your bridge.

Can you ping 10.10.80.50 from your Home Assistant instance?

Hello,

No I have not made progress. I could ping:

10.10.80.254 to 10.10.80.50 (same network) 10.10.30.100 to 10.10.80.50 (user network to ha network)

Telnet connection on the port is also working. But not from the integration. It discovers the device automatically, but when adding it throws unspecified error.

I was following the other topic from Zollak as well, looks similar...

https://github.com/michaelarnauts/home-assistant-comfoconnect/issues/22#issue-1831039521

No idea what I can try...

[sgeeurickx]

Hi' Since the latest release, I no longer have any problem connecting both my devices. Thanks a lot for your work

[Brewery-GIT]

Small Update:

• I did not change any network settings
• I completely redeployed HA from scratch.

Now the integration works directly out of the box.... Thanks for your time on this integration, much appreciated.
