This ensures that the Home Assistant Companion on Android 10 (this is what I tested) will correctly connect to the local Home Assistant instance. This is due to compliance with RFC 2818, which states that support for CN fallback is deprecated and only SAN should be used to establish whether a certificate is valid or not.

Proposed change
This ensures that the Home Assistant Companion on Android 10 and iOS 13 (this is what I tested) will correctly connect to the local Home Assistant instance without blocking the connection due to an SSL error.
This is due to compliance with RFC 2818, which states that support for CN fallback (that is the only parameter we are allowed to set with the current openssl command in the docs) is deprecated and only SAN should be used to establish whether a certificate is valid for a certain host or not.
