Note that the dns record for "news-us.usenetserver.com" is a CNAME with a 5 minute TTL. Could well have pointed to different servers over time, which might explain the intermittent nature of the error.

We need to read out the certificate, can you run this command:

openssl s_client -connect news-us.usenetserver.com:563

Here is the results of that command:

200 news.usenetserver.com Welcome! (fx16.iad)

The problem is not intermittent. It started out that way. Now I can no longer connect to this server without the untrusted certificate error.

Possible DNS Hijack?

Check your sabnzbd.log for lines with "news-us.usenetserver.com" in it, and post them here.

This is from my sabnzbd.log:

I wanted to note that I have changed my DNS servers that my network uses, just in case it's a possible DNS Hijack.

news-eu.usenetserver.com and news-us.usenetserver.com use different certificate issuers:

EU uses GoDaddy, see:
https://www.sslshopper.com/ssl-checker. ... er.com:563

US uses Let's Encrypt Authority X3 / DST Root CA X3, see:
https://www.sslshopper.com/ssl-checker. ... er.com:563

So as your system does not trust the US server, I think your DST Root CA X3 root certificate is missing in your system.
As you are running SAB on Windows (right?), you should
- update your Windows, update again, update, reboot ... in other words: the usual Windows sequence
- you can check your root certificate. EDIT: you need to start a Powershell session, and then type "Get-ChildItem -Recurse Cert:", and in the output search for "Root CA X3".

To verify my hypothesis about the root certificate for Let's Encrypt Authority X3 / DST Root CA X3 missing on your Windows: Can you run these two commands and post the output here:
PS: Oh, you're on Windows. So I'm not sure if you have / can run Python ...

Well, managed to fix it! Thanks to your help, I found that the "Root CA X3" certificate was not present on my WHS 2011 Server. So, I found it on my Win7 machine, exported it to a usb thumb drive, then imported it into my WHS 2011 server. Works fine now!

Not sure why the certificate got deleted or lost.

Thanks so much for showing me how to work with certificates.
