Cannot start server using SSL

[Jzjr]

Hello,

I've recently started migrating my Domoticz setup to an x86 box as I've had a couple of SD card problems with the Pi.

I have compiled the software from source and have everything working as expected apart from SSL access - I am now starting to forward ports so I can log-in remotely.

The error that appears in the log is:
Error: WebServer(SSL) startup failed on address 0.0.0.0 with port: 9443: use_certificate_chain_file: No such file or directory

I am currently using v3.8796.

I have had a search around but most of the errors appear to be due to permissions on ports below 1024, however I've decided not to use any of these ports.

So far I have tried differing port numbers and recreation of the systemd service but it appears the problem lies elsewhere.

Any suggestions would be greatly appreciated.

Thanks
Fred
