Sorry but you are being damn confusing. Why did you then mention 'High Sierra' as your OS below ????

If you truly do have macOS11 installed, fully up to date, then I am very surprised you are seeing SSL issues.... can anyone else on this OS confirm if they see the same issue...

Other than updating the system from High Sierra, nothing else. It sounds like I 
may need to update my certificates?

Oh.... You said you where on macOS 11... I guess that was incorrect and you 
really mean OSX 10.11 or.... what ? High Sierra is OSX 10.13 ... Please try and 
be precise in your OS version as in this case it really makes a difference...

So, assuming you are on 10.11, or 10.13... That OS is indeed old and known to 
have SSL issues. The best solution is indeed to upgrade to a newer OS (for many 
many reasons...)
