Hi, my own server is using a certificate from let's encrypt without any problem.

You shouldn't have any specific parameter to set up on your phone (let's encrypt root certificate should already be trusted by recent android phones)
Can you double check your server configuration? See some tips on this link: https://stackoverflow.com/a/16302527

Please report back if you manage to fix your issue, otherwise show us your server configuration.

Thank you pointing me to the answer. The problem was in certificate. My nginx used cert.pem, that contains only issued certificate. After it was replaced with fullchain.pem, that contains all certificates in chain up to the root, everything works fine!

Thank you very much for your answer and sync client! Hugs!
