Mono trusts everyone except Google

I am working on an app that uses Google's services over SSL. However, when trying to connect I get the following exception.

System.Net.WebException: Error: TrustFailure (The authentication or decryption has failed.) ---> System.IO.IOException: The authentication or decryption has failed. ---> System.IO.IOException: The authentication or decryption has failed. ---> Mono.Security.Protocol.Tls.TlsException: Invalid certificate received from server. Error code: 0xffffffff800b010a
at Mono.Security.Protocol.Tls.RecordProtocol.EndReceiveRecord (System.IAsyncResult asyncResult) [0x0003a] in /build/mono/src/mono-4.6.1/mcs/class/Mono.Security/Mono.Security.Protocol.Tls/RecordProtocol.cs:430

I am running Mono version 4.6.1 on Arch Linux. Chrome and Firefox have no problem connecting to google.com over https.

I have followed the steps here to make sure the Mono's certificate store is in sync with my system's certificate store. I made sure that ca-certificates was installed and then I ran both cert-sync /etc/ssl/certs/ca-certificates.crt and mozroots --import. I then tried using the tlstest.exe tool to test SSL connections to various websites. It succeeds in connecting to every site I could think of except google.com. This includes github.com, arstechnica.com, stackoverflow.com, nuget.org.

Here is what happens with Google.

$ mono tlstest.exe https://google.com

I'm not sure what to do at this point.
