Hi,

When browsing to the duplicati URL, I have valid ssl connection (valid certificate) but the page does not load, it is going in a circle.

From systemctl status, I have :

Critical error occured : System.PlatformNotSupportedException: Operation is not supported on this platform.

But when I dont use ssl options from /etc/default/duplicati, it works using http.

What could be the issue ?

Thanks in advance !

What version of mono are you using?

This thread may be relevant: Latest Mono not supporting SSL correctly

It offers a workaround. I’m not sure if this issue has been fixed or not in Duplicati.
