SSL not work in EasyIoT server

Finally I installed the EasyIoT server, following the steps indicated in the installation of the package. I generated the files for the SSL connection and followed all the steps, but I can not get through port 1301. The files (root.cer, root.key and raspberry.p12) are correctly located in their directories and are only accessible by root . What do I need to configure to support SSL connections?

Thank you for your help

Hi, have you found the solution for your issue? Looks like I hit exactly the same problem. 

probably the issue was too old mono. 
Although I did not test it on my Rpi2 but bought Rpi4, so the latest mono there. SSL (self signed cert) works like a charm
