Since a few weeks/months the companion app does not work anymore, I got errors that the certificate was not valid, but if I checked the certificate in the app, the validity was still a month.
I removed the app, resetted the app and removed all frontend information. Now I wanted to start fresh with an app, but I installed again and want to configure it but get an error (Big red cross).
Unknown error: URLSesstionTask failed with error: The Certificate for this server is invalid. You might be connecting to a server that is pretending to be “my host” which could put your confidential information at risk.
When I grab another iOS device and install the companion app i can configure the app without an issue. So my device seems somewhere to keep old information or in Homeassistant which makes it impossible to use the companion app.
Things tried
Update homeassistant to newest stable version
Checked homeassistant setting in ios, it is allowed to use the network
Restarted device
Removed app/ reinstalled again.
What can I check, as i cant reconfigure the app on my phone, I cant check any logs on my device.
