Let's encrypt on a live system and a webserver in a Snap?

Question

Web servers

Good afternoon.
The thing is - I installed a snap-package with Rocketchat on Ubuntu 18.04, set everything up, forwarded the ports, got the domain name fixed, registered the DNS.
The problem is getting an SSL certificate, I can't pass the verification, because Rocketchat is spinning in a snap package and certbot can't create a .well-known folder to verify the owner.
How can this problem be solved? Maybe install certbot in the package and run from there?
Help me please.

Answer 1

Use verification not through a file, but through DNS. This is longer than the file, but not in your case.
You get something like certbot -d domain.com --manual --preferred-challenges dns
