Trying to use SSL on an owinselfhost Running under windows(Xamian) works fine, but under Linux it causes an unhandled exception. I've posted a question to stackoverflow that details what I've done and some code associated with it:
If needed I can embed the full commentary in here, but why duplicate?
I'm pretty sure this is the same problem as in #46602. I merged a fix for that recently, it should be included in the most recent Mono 4.8 preview refresh. Make sure you have Mono 184.108.40.2069 or later installed.
I'll close this as a duplicate of that bug now, please try if your issue is fixed as well. Thanks!
