Lets Encrypt Root Certificate Fix

Due to the expiration of the Lets Encrypt root certificate all v1.29 versions of Pritunl containing the expired certificate will no longer produce a valid certificate. Having an invalid certificate will not disrupt VPN service. The primary issue will occur when a user attempts to import a new profile to the Pritunl Client. Both the Pritunl Client and Pritunl Server need to be updating to the latest releases containing the new root certificates to fix this issue.

The issue can easily be avoided by clicking Download Profiles on the profile page then importing the tar file into the Pritunl Client by click Import Profile, this is the same profile data that would be imported with a URI. The issue can also be avoided by replacing the domain name in the URI with the IP address of the server. The client will ignore certificate validation for URI's containing an IP address.
