If sub-domain ends in a hyphen then wild-card certificate is rejected
- jsingleton 10y agoI came across this while building the ASP.NET Core Library and Framework Support matrix (https://anclafs.com https://anclafs.com). One of the contributors has a hyphen suffix on their GitHub name so their pages site has that as a sub-domain. The *.github.io cert is rejected in Firefox. Try https://ah-.github.io/rdkafka-dotnet https://ah-.github.io/rdkafka-dotnet versus http://ah-.github.io/rdkafka-dotnet http://ah-.github.io/rdkafka-dotnet in FF47. Obviously a pain if you have the HTTPS everywhere add-on.
