502 Bad Gateway (nginx) after Update to 2.3
-
Has anyone been able to figure out what is happening with this. I get this every couple of days and the only resolution is to take the 20 minute walk to physically restart the firewall.
I can log in using ssh but the majority of the commands either give an error on execution or don't work. When I log in I don't get a menu. I start the menu with /etc/rc.initial
After that if I use options 11 or 16 I get errors
Restarting webConfigurator…Error: cannot open /var/etc/nginx-webConfigurator.conf in system_generate_nginx_config().Fatal error: Call to undefined function pfSense_interface_listget() in /etc/inc/interfaces.inc on line 80

I have also tried /etc/rc.initial.reboot
Again I get the prompt asking to proceed but the system does not reboot.This is costing me too much time.

Just upgrade to 2.3.1_1 which was released today.
-
I had the same issue even with 2.3.1-1. I dont have the openvpn widget open. I shut down the PFblockerNG and Snort widgets to see if they are the culprit. I am left with system information and interfaces.
-
since upgrading from 2.2 to 2.3.1 I've been getting "502 Bad Gateway" error at least once a week which I correct by starting PHP-FPM, but this is getting very annoying especially because it causes some of my sessions to drop, does any one know of any permanent fix?
2.3.1-RELEASE-p1
IPsec
OPenVPN
PfBlockerNG

Same here. Will try tomorrow without the ipsec widget for reference.
-
I'm also seeing the 502 Bad Gateway error. I'm running 2.3.1-RELEASE-p1 (i386 nanobsd) as a direct update from v 2.2.6, hardware is a Soekris net6501. Installed packages are Network UPS Tools v2.3.0 and openvpn-client-export v1.3.8.
When it hangs up I log in via SSH and choose the 16) Restart PHP-FPM item from the text interface. As per others on this and other threads I have removed the IPsec widget from the dashboard to see if that helps.

I have received the 502 Bad Gateway error after upgrading to 2.3.1 Release.
I have the IPSec widget open. I will have to restart the firewall after working hours today, and disable the widget and see if that solves anything on our end. -
I am still getting this error even after upgrading to 2.3.1_1
It has happened a couple of times now. I have also noticed that when it happens and I SSH in to the CLI I have to run sudo rc.initial to get the menu up. (If I don't run sudo none of the commands will work). I can then reset PHP and get access. -

As you say, you have to sudo (to become root) and run the rc.initial script (the menu).

OK. But how about the 502 error. It was my understanding that 2.3.1_1 was supposed to fix that problem

I believe there are still possibly some cases where the IPsec widget is doing back-end requests, those hang (or take a long time) and make all the PHP processes busy.
If you have the IPsec widget enabled on the dashboard, then remove it. Report back if that stops the problem. -

Getting 500 error here

I haven't seen this error before today - here's the background. My old NetGate Alix box died and I replaced it with a new box and installed 2.3.1-RELEASE-P5 with the WAN port connected to my office LAN, installed AutoConfigBackup and pulled the old config file off the server. I setup the new interfaces and had no problems at all - there are no other packages installed, no VPN etc - it's a basic, single WAN firewall with a few custom rules and two separate LANs - I've been running on a 10 year old Alix so nothing fancy at all. Everything went really smoothly - until I took it home and installed it.
For some reason (probably a different MAC address) the firewall is not pulling a DHCP address from the to the COX cable modem - I was able to log in just fast enough to see that once, but otherwise - I'd guess 95% of the time - I get the 502 Bad Gateway (nginx) error message when I try to access the GUI via the LAN with the cable modem connected. The error goes away if I reboot with the WAN disconnected, I can access the LAN interface if I disconnect the cable modem, so I wonder if the problem is related to something in the firewall seeing the WAN port "up" but not actually passing any data.
-
@edmund Perhaps the cable modem is giving a (private) IP address/CIDR that matches/overlaps with the LAN subnet?
Although I realize that if you are using an old config from the Alix that was working, that should not have been the case.

My experience with cable modems has been that a DHCP request appears to cause them to serve the assigned IP address if the requesting device has a MAC address recognized by the modem. That was they way that it appeared to be working previously with pfSense displaying the actually cable company IP address in the WAN status.
I suspect that this is just a configuration issue - what I found interesting here is that I'm getting the 502 bad gateway error (to be expected since the WAN was not serving an address) and it's causing me to be locked out of pfSense until I disconnect the WAN.
I think that my next step is to return the new box to the factory configuration and set it up again from scratch to ensure that there are no Alix specific switches in effect.
-
I did a factory default reset and started the setup again. Something seems to be very wrong with pfSense - I'm seeing an average CPU utilization of 25% with no traffic on a 4 core box with two cores running at 100% - see the attached picture. The WAN gateway appears to be dropping up to 80% of the packets - yet switching from the pfSense box to a Linksys router gives my about 70M/10M on a speedtest - it's not the modem or connection that's causing the problem.
With this new setup I've completely disabled IPv6 (at least as far as I can tell) and the 502/504 Bad Gateway messages have stopped although pfSense still shows the gateway as down on the widget. Also unbound crashes a lot - you can see each CPU running it's own copy of unbound - is that normal?
After four hours with no progress I think it's probably time to wipe the disk and start again from scratch.
-
I believe that the root of all my problems has been an auto-negotiate failure on the WAN interface - after replacing the WAN -> modem cable with a CAT6 cable it's connecting and finding the interface without problems. The rest of my issues here probably stem from my futile attempts to "fix" the hardware problem with changes to the software settings.
The lesson is - just because it's got four pairs doesn't make it a CAT6 cable.

Experiencing the same problem as the OP.
I'm in the process of setting-up a brand-new pfSense firewall. I have two IBM x3550 servers in an HA configuration. New install using 2.3.2. All my interfaces, except the SYNC interface, are VLAN interfaces.
Almost immediately I started encountering the "502 Bad Gateway (nginx)" error in my web browser. The pattern I've seen is it's always preceded by changes to interfaces, and before it locks-up fully with the 502, I consistently get a crash report with numerous errors like "PHP Fatal error: Call to undefined function pfSense_interface_listget() in /etc/inc/interfaces.inc on line 80".
The PHP error mostly happens on the backup node after I make changes to the primary node and it syncs to the backup. The primary node produces the PHP errors less often, and locks-up with the 502 error very rarely.
I'm curious: is this problem recognized and fixed in version 2.3.3?
Thanks!

I am also hitting this issue I think. Running 2.3.2; now getting 502. Restarting PHP-FPM did not resolve this. Will reboot tonight, disable IPSec widget and report back.
Having a hanging check_reload_status pocess:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 293 root 1 123 20 31176K 15508K CPU1 1 131:47 100.00% check_reload_statusUpdate
After forcefully terminating check_reload_status I could salvage the web GUI, though many services seem to be in a broken stateUpdate 2
Rebooted the firewall. One of our VDSL modems died witch caused a lot of resyncs. Swapped it for a good one. Might be related?I believe that the root of all my problems has been an auto-negotiate failure on the WAN interface - after replacing the WAN -> modem cable with a CAT6 cable it's connecting and finding the interface without problems.
