to see the results… I will reply asap

Did you try to change your old redirect URL "http%3A%2F%2F172.16.0.1%2F" == "http://172.16.0.1/"
to "http://www.google.com" instead of changing the source ?

What pfSense version ? - is it patched or modified ?

The same here.
After re-applying the squid settings it stopped to logs the errors, but after 2 or 3 days (depends on load) it reappears

I experienced this also in latest pfsense right now. my captive portal disconnects .I hope there is a fix for this.

@dyobetem I also have this issue since 2 months and its related to Captive Portal. i have 2500+ captive portal users and 2 WAN. i changed a lot of settings in nginx but useless. still i am getting these errors. I've pfsense 2.4.4-P3 Lastest version.

i have already mentioned this issue in given blow post ( last Issue )

@wazim4u : Do you redirect a new, just logged-in user to an URL ( setting After authentication Redirection URL ) ?

This is what I think : when a user logged in using the IP (or URL) of the captive portal page, the users browser gets redirected to the same URL (== the captive pprtal's web server).... which will redirect again - to itself -, and again, and again etc - recursif. The URL thrown back to the browser becomes to big, nginx will finally produce the "send() failed (40: Message too long)" error.

For myself, I redirect, no matter what, to "https://www.google.com" but you can take any URL like a your companie's site.

Another explanation : you have quiet a lot of portal users. Not every user uses the latest smart devices /PC's with the latest OS and the best browsers.
Even I see still IE8 (Windows XP) connecting to my portal.
These ancient devices are not portal aware. They won't behave correctly.

Or even : not all the apps are written the same way. At least, Apple reviews (some what) each and every app before it's released - the Android society is a pure zoo. So, a bad app can throw out an URL that's to big. nginx will bail out.

So, mind you, these are all theories.
I do not have the test park to test them.

This issue has been resolved?

I have this same problem

Gertjan

@andresense

Sure.
No news after more then one year : that means : no issue.

We are also 2 (at least) version of pfSense further on.
