I want to use Serilog together with LogEntries. This works fine when I run the App on a Windows PC, but when building and running on mono on ubuntu 14.2 no messages are received at LogEntries. As a second slog sink I have configured console output and this works on Linux.
After turning selfdebug on in serilog I got this Exception logged:

Which looks like there is an SSL Issue in combination between Mono and Logentries.
It may just be easier to use the Linux Agent to follow the log file which is created. The Agent would then forward this log data to your Account.
