Vaultwarden + https not working on android


I’m self-hosting a vaultwarden docker. I got an nginx working and redirecting vault.lan.dns to my docker instance with an entry in my local dns adressip A vault.lan.dns

i do connect to it with https on web or web extension on my computer, but i can’t get it to work on my phone application.

i imported the .crt i self generated with openssl but still got this error : exception message: hostname vault.lan.dns not verified : certificate, xxxxx whatsoever.

I kinda need some help there !

Do you have the full cert chain when you imported it?
I am also not super sure how the clients handle non-standard domains such as lan.dns
