Unable to disable https redirect for web connections

    According to instructions in article AR07P00986, we should be able to disable https redirects when attempting to access nxwebplayer via http://ipaddress:4080, but these instructions appear to be out of date and are no longer applicable. I attempted many variations of this by modifying htd.cfg as indicated, but nothing seemed to produce the desired result, always giving an error message related to using http to communicate with an encrypted server, or a generic internal server error.

    To give a little background, I have Caddy providing encryption for several other services already, and it requires ports 80 and 443, so giving those ports over to NoMachine entirely is not a great solution for me.  If I can get NoMachine to serve over unencrypted http in the browser, I believe I can get Caddy to provide the encryption from that point.  I’m relatively new to this world of servers and services, and I am just experimenting really, so please feel free to let me know if I’m doing something stupid.

    For reference, I’m using NoMachine enterprise desktop evaluation, version 7.1.3, in Windows 10.

    P.S.  You guys are awesome, and thank you for NoMachine, been using it for years.


    I tried a few more things, and finally found a configuration that would disable the redirect successfully.  That said, I am still having difficulty getting Caddy to serve the webplayer successfully through a reverse proxy to a subdomain.  It will load the webplayer, and log into the remote computer successfully (PC shows popup notification that user has connected), but will not actually load the picture remotely (all is successful if logging in from LAN using direct IP in browser).  I’m not yet sure if it’s a limitation of Caddy, or if I need some additional configuration on one side or the other.  If anyone knows anything I can try, I would greatly appreciate it.

    I’ve copied the relevant block from htd.cfg below, in case it can help anyone else out.
