Firstly it appears you have not correctly configured the virtual host newspaper.latvijai.lv to handle LE http-01 challenges for that domain (all the others are set-up automatically by Virtualmin). A quick google / search on these forums will give you the answer.
As for wildcard issuance, which can only be done using LE DNS challenge mode.
LE queries are directed to the public nameservers specified as authorative for for the domain therefore you wont be able to manage this unless (@Joe - this means DNS has to be hosted as explained below - it can be either local or remote):
1.) You have correctly set-up, configured and use the server requesting the LE wildcard certificates as the public authorative nameserver for the requested domain.
2.) You have correctly set-up, configured and use Virtualmin slave DNS servers as your authorative public DNS servers while your LE certifcate requesting server has permission to push DNS change to those servers (if using Virtualmin Master->Server DNS this is automatic) (a challenge / authorisation key is created at issuance request as a DNS record to prove you have control of the domain, and this record is then queried by LE at issuance - no / incorrect record and the issuance will fail!).
3.) You are using public DNS servers which can be updated in realtime by the server requesting the LE certificates (a challenge / authorisation key is created at issuance request as a DNS record to prove you have control of the domain, and this record is then queried by LE at issuance - no / incorrect record and the issuance will fail!)
If choosing wildcard certificates remember to select and specify the correct options in virtualmin:
These forums and / or google contain all of the information you’ll require to implement LE certificates using http-01 or DNS challenges.
