I have noticed that if you use self signed cert the plugin doesn't want to connect to the HA.
I made self signed cert due to few issues that make it not possible for now to use something like let's encrypt.
I have cert files that allowed me to add my cert as trusted with android device... would there mayby be a way to do the same in opendeck? I assume opendeck HA plugin uses invisible browser or something like that, so here I be not sure would somehow adding it as trusted on my pc would change anything.
