Description Alex 2017-03-27 14:36:13 UTC
Locations issue tested: Raspberry pi, a larger linux server, Mac, and Windows (all with command line Mono usage)

Description of issue: We have written some scripts to access Targetprocess' API to help with our CI process at my company. We use .NET to write small programs and run them on linux servers (be them a small pi or something larger). Right now we are able to run our programs on our Windows machines natively from VS successfully, but should we try to use mono on any platform we see errors (typically very clearly stating TLS issues)
*Knowing that it very well could be our script we also see the errors reproduce using the tlstest.cs instructions provided on the Mono.Security site.

Reproduction: On Linux/RPI I've updated to 4.8 using apt-get and then tried running the tlstest.exe test. Should I point at https://google.com, we see a response of the website. Should I switch over to trying to access our instance of targetprocess - we see the response below: (this is after setting - export MONO_TLS_PROVIDER=btls)

pi@rpi-test-1:~ $ mono tlstest.exe https://www.skyward.tpondemand.com/

Thank you so much for your help and I can be more or less thorough as necessary!
