Hostname not verified exception (Utility.MatchHostnameToPattern not applied for certificate alt names)

Logan2014 commented 4 years ago

After I update NuGet package from 2.7.2 to 3.3.4 version I got "Hostname prod-25.westeurope.logic.azure.com not verified exception". For one of my endpoints.

I made some investigation on this issue. The problem is in method that verify hostname :) Server certificate contains subjectCn=westeurope.logic.azure.com and subjectAltNames=[westeurope.logic.azure.com, *.westeurope.logic.azure.com]. Method which check hostname uses Utility.MatchHostnameToPattern method to verify subjectCn name and simple Contains method for string array to check subjectAltNames. None of this verifications allow to use prod-25.westeurope.logic.azure.com hostname.

Resolution for this issue is application of MatchHostnameToPattern method for each subject alt name.
