Command line documentation, how to switch https on and off?

[opn_mdrescher]

Hi members,

I have an OPNsense 19.1.10_1-amd64 in hand, which is running plain http. I was told, there was "a problem with HTTPS", what ever that means...
However, I can not risk breaking the HTTP/HTTPS interface, so I was looking for a command line option switching https on and of. Is there any documentation about command line administration, where to find?

Or, may be, some one could just tell me, how to switch? Cert & key is in place and known to be good.

There is no toggle in the config but if you reassign the interfaces, it allows you to revert to HTTP.
