I know I'm piggy-backing on jmannz's thread and I'll start one of my own if you want, but if you were talking to me, I get the error on every one of my web pages. One example is:
It's the same error I get on jmannz's URL above:
"The certificate for rednoise.x10host.com expired on 5/10/2025. Error code:
SEC_ERROR_EXPIRED_CERTIFICATE"
I have the option to add the page to Firefox's list of exceptions, but that just masks the real problem, I reckon. I can view the certificate and paste it in here if that would be helpful.
I'm also having trouble connecting to my x10host email address with Thunderbird via IMAP. I assume that's related. I'll start a new thread for it soon.
