Hi @Co6aka

Detail: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.blagodareva.lavnik.net

checking your domain you have created the wrong entry ( https://check-your-website.server-daten.de/?q=blagodareva.lavnik.net#txt ):

The menu you use adds your domain name.

So you have created an entry with a duplicated domain name lavnik.net.lavnik.net.

Create an entry with

_acme-challenge.blagodareva

as name, so the menu adds the domain name one time.

thanks, all worked well

Yep, now you have a new Letsencrypt certificate:

CN=blagodareva.lavnik.net
	07.07.2019
	05.10.2019
expires in 90 days	
blagodareva.lavnik.net, www.blagodareva.lavnik.net - 2 entries

Happy to see that it has worked
