Risco cloud is blocking the HA user agent

[XalaTheShepard]

The problem

Dear maintainer,

My Risco integration suddenly stopped working overnight.
The Risco Cloud app still works and no maintenance has been done, nor new devices added.
I had a look at the open issues, and the logs indicate a different issue.
Please find the logs below.
Could you please have a look at this issue?

Many thanks in advance.

Kind regards,

Robin

Same here, home assistant versions:
Home Assistant OS
Core 2026.4.1
Supervisor 2026.03.3
Operating System 17.2
Frontend 20260325.6

Risco stopped working this morning and I have these logs:

My credentials work fine from RIsco Web Page and the iRisco app is working, so my Security System is connected.

[vidanware]

I'm experiencing the same issue on Home Assistant 2026.4.1. The integration fails during the login process with a ContentTypeError: 403.

I have verified that my credentials work fine on the official Risco website and mobile app.

@simille83 , now we can already exclude that this issue is related to HA Core 2026.4.X . Most likely an issue or change from Risco's part

I tryed from Postman the login endpoint and it works fine, seems that the response payload is the same..

[HAatHome]

Same here. Risco stopped working this morning at 10:52 this morning.
My credentials work fine at all Risco Clients except Homeassistant.
This is not a problem with HA Core 2026.4.x

I have the following installtion:
Core: 2026.3.4
Supervisor: 2026.03.3
Operating System: 17.1
Frontend: 20260312.1

[beckr]

Duplicates of #167628 ?

[XalaTheShepard]

@beckr no duplicate. Different issue and error log. The key in this issue is that it started today for all of us. The other topic happened two days ago.

[Armitage00]

Same here.

[OnFreund]

@home-assistant rename Risco cloud integration not working due to API change

[OnFreund]

Looks like an API change - I no longer have a cloud subscription or access, so will need someone who can help with this. Is there anyone who's comfortable running proxy for their phone app to monitor communication??

Everyone else, no need to post "me too" - we don't want the noise masking the signal.
