Problem with the Solax integration

[tarrinho]

The problem

I'm having an issue with the solax integration:
I'm able to connect to solax (http://ip/api/realTimeData.htm - error code 200), but when I try to add the device in the Integration part (SolaX Power), I receive the note that it doesn't work (Unexpected error). So I decided to had a reverse proxy (Apache), and what I see is:
"GET /api/realTimeData.htm HTTP/1.1" 503 506 "-" "Python/3.12 aiohttp/3.9.3"

What version of Home Assistant Core has the issue?

core-2024.3.1

What was the last working version of Home Assistant Core?

not sure, but 1 year ago, it was working

What type of installation are you running?

Home Assistant OS

Integration causing the issue

SolaX Power

Hello,
any news? Is there any other information that I can supply that would help?
Thanks

[tarrinho]

Hello Robin (@squishykid ),

did this integration stop working?

Thanks,
Pedro

2024.5.0 has solax 3.1.0 which improves the discovery process by, among other things, consolidating identical requests.

The version of the library in your older HA instance could very well have spammed the inverter to the point it becomes unresponsive for a bit.

Consider updating, or creating a test instance with 2024.5.0 and see if that helps.

Did the upgrade:

Same error:

[dretful]

Same error as tarrinho. Would be grateful for a fix?

[lstolcman]

should be fixed with #115129

[japeral]

should be fixed with #115129

Same problem here why #115129 was closed? muppets.

what can i do?

Did the upgrade:

Same error:

I got it after the last update solax cloud. you can find the password under: Devices - "your Inverter" - klick the tree points and Backup password. That`s the password you need and the correct IP of course. port 80 is ok.
