How to import a Let'sEncrypt certificate for Bitbucket ?

[sogvicious]

Good evening, first of all I introduce myself. My name is George and I am new to this community, and I am grateful for any help you can give me.

I'm trying to import a certificate created with letsencrypt for an instance of Bitbucket Server on Tomcat under Ubuntu 16.04, and I can not import the certificates (cert.pem, chain.pem, fullchain.pem or privkey.pem) and I can not make it work.

Did someone have this situation and managed to solve it?
