[SOLVED] Linux Wiki is unsecured site for sign in, Firefox tells me. True? Fixes?

From Xubuntu 20.04, running an Optiplex 780 SFF, 8 gigs RAM

Firefox says Linux Wiki is an unsecured site. I do not have my protocols really set for security on this new distro, yet. I am learning how, still. I didn't join,because of that warning.

Firefox recommended adding https:// to the beginning. No help. Is this a real problem? Can I fix it on my end?

Got some irrelevant(to me) questions that were "similar" to mine, but not really.

got this

https://support.mozilla.org/en-US/kb...urce=inproduct

Would share screencaps but I am new and don't have that privilege yet.

Thanks for the help, and this is about as concise as I ever am, so apologies ahead of time.

Can you post the URL or Wiki site?

There is a firefox addon "https everywhere". I suggest you install that (but dunno whether that helps in this particular case).

I tried opening https://wiki.linuxquestions.org/wiki/Main_Page in Firefox just now, and I get

Secure Connection Failed An error occurred during a connection to wiki.linuxquestions.org. SSL peer has no certificate for the requested DNS name. Error code: SSL_ERROR_UNRECOGNIZED_NAME_ALERT ...

So I guess there is some misconfiguration on the server.

curl -vLI  https://wiki.linuxquestions.org/wiki/Main_Page

There is no cert for the wiki at this time. We'll add one after some other changes are made.

Thanks, I think we can call this solved, I think. So glad it wasn't me. For no obvious reason.

Been there, done that.
A suggestion: Redirect the wiki. subdomain to a url without the sub domain that is covered by the existing certificate that points to the same space.
Don’t need to change any links or expand the certificate.

(We had abc.mydomain.com When we secured my domain.com, we just Redirected to mydomain.com/abc)
