I am new to LE and my problem seems to be similar to other DNS validation problem.
However I cannot manage to find the problem. Here is the error message :
Failed authorization procedure. liris.lemni.top (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: SERVFAIL looking up A for liris.lemni.top IMPORTANT NOTES: - The following errors were reported by the server: Domain: liris.lemni.top Type: connection Detail: DNS problem: SERVFAIL looking up A for liris.lemni.top
I also read that it could be linked to uppercase and lowercase letter but it does not seems to be a thing here :

I don’t really have any clue that can help me there…
