ColdFusion 2016 - Error on Server Settings page in CFAdmin

I hear you saying you’re not a CFer, so this may get a bit confusing (depending on your experience with any other server software), but here goes.

Your error shows you using a URL to get to the CF Admin which refers to using port 80 (well, you use no port, so that defaults to 80), which means you’d be trying to access the CF Admin via IIS, I assume since you’re on Windows.

But CF2016 no longer supports access to the Admin through IIS or Apache. Instead, you must use CF’s built-in web server, whose port was selected during installation (more in a moment). And in fact if you try to access CF2016 , it should fail differently than what you show below. I suspect that somehow your IIS is still set to pass requests to your CF11, and this is CF11 complaining.

But regardless, if you installed CF, and as you say you’re on Windows, hit the Start menu, then choose Adobe then ColdFusion 2016. You should see a link to the Admin there. Open that. It will open the URL that CF thinks should be used, using the port for CF’s built-in web server that was chosen during CF 2016 installation, likely 8500 or 8501 (depending on whether the person installing CF11 had chosen to use the built-in web server, as it was optional then).

If that gets you into the CF admin, does your page then work?

If not, or if you would assert that you had been using the correct URL all along, then I suspect your problem is that you applied a CF 2016 update after installation, and that has left things broken. I have a blog post on how to confirm and recover from that:

And if you remain stumped and don’t want to wait for back and forth among folks here, I’ll note that I offer quick online help for such problems. I suspect we’d be done in as little as 15 mins. More on the consulting page on my site.
