TLS 1.2 - is there a place within Robohelp that one can control the TLS settings once the help project is published to the server?
Not that I'm aware of - that's a server-side setting I believe.
"Is there any way for me to provide some kind of proof to my sysadmin that Robohelp DOES NOT affect TLS settings on the server?"
- RH's just generating HTML5 pages - from my understanding, TLS has more to do with certificates that are present on the server & the choice of the TLS level to be used on the browser.
I believe this sounds reasonable. I had a few sysadmins walk thru the published help project looking for any config files. found only one, and it had nothing in it at all regarding TLS settings. All literature suggests TLS is set on server side, not on client side.
