PHP 502 errors as of June 6 2025

P_Speers · 10 June 2025 01:47

After running ./daily.sh some of the errors have cleared but I still have the “PHP Error(2): stream_socket_client(): Unable to connect to tcp://127.0.0.1:6379 (Connection refused) in /opt/librenms/vendor/predis/predis/src/Connection/Resource/StreamFactory.php on line 209” error immediately after the [OK] MySQL and PHP time match in the ./validate.php output.

Your redis server is not connectable. I’ll catch that error so we can make a nice fail message instead.

P_Speers · 10 June 2025 02:12

I ran sudo ss -tnlp and port 6379 is not in use, I guess that explains the connection refused.

alright, redis fixed.

but page /alert-rule 502 error

nginx error log

2025/06/10 14:32:27 [error] 3196370#3196370: *49 upstream sent too big header while reading response header from upstream, client: HIDE, server: HIDE, request: “GET /alert-rules HTTP/2.0”, upstream: “fastcgi://unix:/run/php-fpm-librenms.sock:”, host: “HIDE”, referrer: “HIDE”

hartred · 10 June 2025 11:41

alright,

fastcgi_buffer_size 128k;
fastcgi_buffers 16 128k;

fixed for me

murrant · 10 June 2025 12:37

That is certainly one way to work around the issue. But doesn’t help get the problem fixed. I want to get these cleaned up before the next release.

Error messages should be in the nginx error log. If you can post them that’d be great.

chriso1013 · 10 June 2025 13:32

Thanks so much for looking into all this Tony. I’ve re-run daily.sh and can see that the changes from PR #17810 have come through - validate.php says my version is now 25.5.0-105-ga79daad87 (2025-06-10T04:25:10+01:00), but I do still get a 502 on the alert rules page without the fastcgi_buffers workaround. nginx error logs are:

PHP Error(2): Undefined variable $device in /opt/librenms/includes/html/modal/new_alert_rule.inc.php on line 48;
PHP Error(2): Undefined variable $rule_extra in /opt/librenms/includes/html/modal/alert_rule_list.inc.php on line 57;
PHP Error(2): Trying to access array offset on null in /opt/librenms/includes/html/modal/alert_rule_list.inc.php on line 57;
PHP Error(2): Undefined array key "required" in /opt/librenms/includes/html/modal/edit_alert_transport.inc.php on line 83;

I’m not getting 502s on any of the other pages we use, but can see other php errors in the nginx log if they’re of any use:

PHP Error(2): Undefined array key "name" in /opt/librenms/includes/html/functions.inc.php on line 647;
PHP Error(2): mkdir(): File exists in /opt/librenms/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php on line 652;
PHP Error(2): Undefined array key "error" in /opt/librenms/includes/html/functions.inc.php on line 697;
PHP Error(8192): htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated in /opt/librenms/includes/html/table/alerts.inc.php on line 205;
request: "POST /ajax_table.php HTTP/2.0", referrer: "https://<my-server>/overview?bare=yes"

Thanks again.

I apologize for interfering, the problem with redis is still relevant

This morning I am getting the 502 error when trying to open Alert Rules, everything was working fine yesterday, seems to have started after daily.sh ran.

taylorcb · 10 June 2025 23:50

I’ve been seeing the “Unable to connect to tcp://127.0.0.1:6379 (Connection refused)” error in ./validate.php, and the 502 errors when trying to access the Alert Rules area in the UI.

Just to rule out some residual thing in my server (it was an upgrade from Ubuntu 22 to 24, plus a few PHP upgrades), I built a new server from scratch, this time with Debian 12. From what I can tell everything is working with this new server, including the Alert Rules area of the UI, but yet I’m still seeing the error in ./validate.php:

Can anybody provide an update on if the ./validate.php error is an indication of a problem somewhere else, especially since it appears my UI is working with a new build? Thanks!!

kanokc · 11 June 2025 01:17

After the last night’s update, the GUI works, but not all pages are loaded. I’ve got 502 Bad Gateway on Apps → Overview menu

And there is PHP Errorr(2) in from validate script as others.

I’m not seeing any impact on usability except getting a 502 on the “Apps Overview”-page (at least from what I’ve seen so far), the individual “Apps”-pages seem to work fine.

The nginx error-log spits out the following when browsing to the “Apps Overview”:

Confirming this also fixed for me;

Edited /etc/nginx/fastcgi.conf and added;

fastcgi_buffer_size 128k;
fastcgi_buffers 16 128k;

To the bottom of the file, then service nginx restart and happy days!

validate.php is still throwing errors, but not getting 502’s everywhere so

I implemented the posted parameters in the Librenms environment, which resolved my issue. Thank you for the reference.

Yes this has worked for me too, thanks alot @hartred!!!

murrant · 11 June 2025 15:55

We are still working on fixing as many of the newly exposed bugs as we can. The most common ones should be fixed. Make sure you are up-to-date and post your errors from nginx error log.
