[choopyat25]

Dear Team ,
Could you please advise on how to resolve this issue. After upgrading to version 26.1.xxx, this error occurs and the services fail to start.

What wrong? Can you explain so that others can avoid?

[choopyat25]

Yes, of course. The problem is that when you add a new server to the DNS-over-TLS section, you need to double check all the rows.
My mistake is -
Server IP: 8.8.8.8
Server Port: 853
Verify CN: dns.google <--IT'S CORRECT NOW, but I entered the wrong name.=)

Than all. =)
Have a great day!
