Hello Andrey :slightly_smiling_face:

Those IP addresses don't match what I'm seeing:
rdsh01.ladesol-tambov.com. 21599 IN A

See rg305's explanation below for more details.

Based on my visits to rdcb01.ladesol-tambov.com, rds.ladesol-tambov.com, and rdsh01.ladesol-tambov.com as well as JuergenAuer's analysis below, your certificate appears fine.

You just need to add http to https redirects.

Did you create that A record very recently?

DNS looks OK at this time.

FYI: You ran the nslookup command using an internal DNS server and it returned an internal (non-routeable) IP - you should use global DNS for such checks:
nslookup rdsh01.ladesol-tambov.com

Hi @Andrei9385

checking your domain looks like you have found a solution - see https://check-your-website.server-daten.de/?q=rdsh01.ladesol-tambov.com

There is a new certificate:

expires in 90 days	rdcb01.ladesol-tambov.com, rds.ladesol-tambov.com, rdsh01.ladesol-tambov.com - 3 entries

and you use it.

Looks good :+1:


Thanks, problem solved !)
