Home Assistant certificate error

Unable to connect to Home Assistant
The date of the Home Assistant certificate is invalid, please review the Home Assistant certificate or the connection settings and try again.

Purely local HA install. I don’t use duckdns or lets encrypt. I only get the error on android. I generated a self signed ssl cert, got the lock in the browser and added it to the android trusted CA but that didn’t help. I can bypass the error by clicking outside of the box and Home assistant works fine. Does anyone have a clue where to look for this bad certificate?

Is the system time correct both for Home Assistant and your Android display?

Yeah they’re good

Check date and time on both HA and Android and make sure timezone is correct also.

Click on settings then go to troubleshooting and look at the logs. It may be an error from another URL on your dashboard.
