I am having a very strange problem where, after connecting to my R500 AP and trying to reach the welcome portal, I get either a 502 Connection Refused or a 310 Too Many Redirects error.
Specifically, the redirection loop happens on the first gateway we set up, HotSpot-RCK-WLAN, which used to work
before we uploaded valid certificates on both the vSZ and HSNM (because we had a https mixed content error during the login procedure, which was not a problem when redirecting to the portal via HTTP).
On the gateway I'm trying to set up now, the connection seems to simply be refused.
All of this seems to point to the hotspot's walled garden not having HSNM's IP or URL, but as a matter of fact, having followed the Gateway Configuration manual available from inside HSNM to the letter (at least I hope so), the walled garden has all the important IPs and URLs, and more just to be sure.
I have put screenshots of all the relevant vSZ configuration, as well as the redirect URL displayed in my browser, in the following Imgur album :
The only bit of information I can gather is the modified redirection URL, but I don't know anything about how vSZ and HSNM communicate and I would love to hear the technical details.
What do you think ? Is there any more useful information I could gather to troubleshoot this ?
