WebGUI returns ERR_EMPTY_RESPONSE after update

[Pollux]

A few days ago I completed and updated to 2.4.3p1. Everything went normally and the WebGUI was normal after the update. Now, the WebGUI is down and when I try and access it all I get is an ERR_EMPTY_RESPONSE.

The firewall is still routing traffic and serving OpenVPN connections normally, so this appears to be only a WebGUI problem.

I have logged in via SSH and reset both the WebConfigurator and PHP multiple times, but that does not bring it back.

Any ideas or suggestions on what I can do to get it back?

Thanks

To add on to this, logs show that nginx is continuously reporting that a worker process exited on signal 11.

Roll the dice and move on up to 2.4.4!

Seriously, if you don't want to do that then create a backup of your config, wipe & reinstall fresh, restore config, reboot, done.

@kom What is the process for backing up the config via SSH?

You're already supposed to have the backup. You don't wait until everything is on fire to take a backup.

I think the current configs are kept in /conf. ssh in and grab /conf/config.xml. Use it to restore from a fresh install and see what happens.

Thanks, I do have a backup from right before the attempted update. Was just curious if there was some way to do it via SSH as well.
