iOS 14 - Error loading page, Domain: NSURLErrorDomain, Error Code: -1202, Description: The certificate for this server is invalid.

I just ran into a cert validation issue when loading a local development server into my webview. Before I updated to iOS 14 this was not a problem and iOS 13.7 had no issues validating the self signed certs that I was using. Suddenly, after applying the iOS 14 update, I am no longer able to load my local web server in the webview using the same certs.

Does anybody know if the TLS cert trust requirements have changed from iOS 13 to iOS 14?

The error I am getting contains the following info:

Error loading page Domain: NSURLErrorDomain Error Code: -1202 Description: The certificate for this server is invalid. You might be connecting to a server that is pretending to be “XX.X.X.XX” which could put your confidential information at risk.
