Hi,
since this morning, I have lost the access to HA via the iPhone app. I get the message “The certificate for this server is invalid. You might be connecting …”. I also tried using Safari instead and after entering my credentials, I get the message “Unable to connect to HA”.
It used to work.
On my MacBook, with Safari and Chrome, connecting to https://xxx:8123 results in a " Your connection is not private … NET::ERR_CERT_COMMON_NAME_INVALID"
If I force the access, I can log in and proceed as usual.
The Let’s encrypt certificates are valid until June 2021.
Can someone help me?
Many thanks
