fab 0 Posted January 9 Share Posted January 9 Hello! I got a message about the SSL of "windows.dns.nextdns.com" it says "the certificate used by this server has been marked as untrusted" NextDNS is a trusted source, why Eset spam warning message ?! Thank you Best regards Link to comment Share on other sites More sharing options...
Administrators Marcos 5,085 Posted January 9 Administrators Share Posted January 9 I'm not getting any warning and SSL Labs report no issues either so it must be a local problem with a revoked cert. or missing a CA root certificate. You can raise a support ticket for investigation as further logs and a list of revoked and installed CA certs will be needed. Link to comment Share on other sites More sharing options...
itman 1,665 Posted January 9 Share Posted January 9 Quote windows.dns.nextdns.com.io This is not a valid domain name. It won't resolve in Firefox or any of the SSL server validation web sites I tried. Link to comment Share on other sites More sharing options...

Administrators Marcos 5,085 Posted January 9 Administrators Share Posted January 9 I prefer using SSL Labs' checker which is most reliable according to my experience: https://www.ssllabs.com/ssltest/analyze.html?d=windows.dns.nextdns.io Link to comment Share on other sites More sharing options...

Using both Firefox and QUALS SSLab Server test, windows.dns.nextdns.io would not resolve when I originally tested. Now, both have no issues.
