      setup a syslogd to a server and the pfSense box is dumping the same error and not the full "too long" message
      "nginx: 2016/11/17 08:36:08 [alert] 38209#100232: send() failed (40: Message too long)"

      What happens for me is I get many of these messages then the system will not allow gui access and affects the openvpn sessions, but other traffic works as normal.

      I'm running a SG-8860 box with the lastest version, no additional packages loaded, one internet connection, 4 subnets, 20 IPSecs and an average of 5 vpn's.

      I need to know what these too log messages are to see what is causing the problem.

              Same trouble with my pfsense after upgrade to 2.3.2 pi1, coming from pfsense 2.2.x
              I didn't installed any Captive portal.
              This issue looks related to the web interface, even if i can't be 100% sure.
              I tried to remove all widgets from dashboard, switch from http to https, and taking a look from shell with "tail -f /var/log/nginx-error.log", an alert entry appears a couple times per minutes, instead once per second as before.

                        @krashneo:

                        I changed my form from:

                        To:

                        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 ?

                        No "help me" PM's please. Use the forum, the community will thank you.
                        Edit : and where are the logs ??

                          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

                                  Aug 28 10:22:38	pfsense.localdomain		nginx: 2019/08/28 10:22:38 [alert] 54908#100145: send() failed (40: Message too long)

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

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

                                      b504e6ad-41e8-4aba-900a-b64db7af5a32-image.png

                                      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.

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

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