Error when trying to connect on iPhone #75

On the getgovroam app I get an error. When I connect to a profile (govroam test), fill in the credentials, I get this error.

@pauldekkers Any idea which precondition triggers this?

I think this is because it's a POST, while it should have been a GET, because it's not an OAUTH eap-config endpoint and in fact based on a static file. I tried to fix this test-profile by moving it from an nginx webserver to Apache earlier, because I noticed Apache didn't mind about the POST going to a static file URL -- but the second invocation uses the If-None-Match and If-Moditfied-Since and (I think!) that triggers the "mid-air edit collision"-filtering in Apache apparently. The profiles in CAT work, because that is actually generated by php, and not a static file.

Tested on: iPhone 11 Pro Max, iOS 16.7

Version: geteduroam version 2.1 (83)

✅ test approved I do not get the error now any more, which is good.
