Hi Chris,

This is probably an issue with SAN certificates. The sites you're trying 
to access probably have changed to SAN certificates or changed the order 
of the domain names listed in them.
If this is the case, then you might want to check your code with the 
solution I posted here[1]. Note that it has been scraped in favor of 
plugin-side certificate verification, but that hasn't been implemented 
yet.
