Description Rafael Cossovan 2017-11-23 12:07:21 UTC
I received a bug report on GitHub complaining that it was not possible to download some favicon from some specific sites.

The issue is this one:

I tried to tracked down the issue, but I don't have much experience with Linux/Mono.

# Steps to reproduce:

1. Download:

2. Compile:
mcs tlstest.cs /r:System.dll /r:Mono.Security.dll

3. Run:
mono tlstest.exe https://www.cdiscount.com

Should work as expected without any errors...

4. Run:
mono tlstest.exe https://clients.cdiscount.com

Should print an error and a stack trace.

The only difference I saw is the certificates are provided by "RapidSSL SHA256 CA" and "Symantec Class 3 Secure Server CA - G4" respectively.

I didn't dig any further.
Any help is appreciated.
