403 Client Error: Forbidden for url: https://www.wemportal.com/app/Account/Login

[M3d1c5]

Hi guys!

The integration has not been able to log on to the WEM portal for a few days. First, the WEM portal was completely down and there was also a 403 error when trying to log in with a browser. This bug was apparently fixed over the weekend. However, the URL calling the integration still seems to be throwing a 403 error. Possibly Weishaupt changed something?

No issue here, restarted server and log is clean and weishaupt data is there.

That is very strange. I have completely removed the integration, restarted the system and then tried to add the integration again. That does not work either. The same error 403 appears in the log.

The smartphone app and the web interface work.

Is there anything I can check?

Is it possible that Weishaupt has banned my fixed IP address? I read in Issue 68 that this has happened before.

My 5 year licence had expired and it took me a few days to get a new licence. During that time Home Assistant kept trying to access the API. Could this be a reason why I was banned?

The normal WEM Portal web interface works, the WEM Portal smartphone app also works, only the Home Assistant integration no longer works.

[dm82m]

I thought about that and yes it is possible. You could write the support and explain the issue

[erikkastelec]

This would be the most likely scenario, as it seems that you are the only one experiencing this issue.

When my IP was banned in the past, I got the same error, but I am not sure if I was able to access the website.

[M3d1c5]

Weishaupt replied to my email that my IP address was indeed blocked. It has now been unblocked and the integration is working again. I was also informed that IP addresses are always blocked if 10000 requests or IP packets are exceeded within 12 hours.

What does this look like with the integration? Does it adhere to the configured API scan interval even if an error occurs during access, such as an expired licence? In my case, the expired licence led to this problem.

[erikkastelec]

Integration does not follow API scan interval when failing so this is the reason for your problem. Will leave this issue open until I implement a fix. Thank you for bringing this to my attention.
