Can't reach Scottish site Rutland wildlife webca.

When I try to enter a Scottish Wild Life Trust I get this error message
when using the Pale Moon browser on Nova:

"This Connection is Untrusted

You have asked Pale Moon to connect securely to
scottishwildlifetrust.org.uk, but we can't confirm that your connection
is secure.
Normally, when you try to connect securely, sites will present
trusted identification to prove that you are going to the right place.
However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error
could mean that someone is trying to impersonate the site, and you
shouldn't continue."

On Nettie I use the 'Google Chrome' browser and can't get through there
either but the error message is completely different:

"Your clock is ahead

A private connection to scottishwildlife trust.org.uk can't be
established because your computer's date and time (Friday, 1 October
2021 at 11:32:10)"

Can anyone tell me what that is all about or better still what, if
anything, I can try to solve it. Incidentally the I get the same error
messages when trying to open the Rutland Water osprey webcam on
www.lrwt.org.uk site.
