[SOLVED] Web admin frontend randomly stopped functioning.

[teward]

So, I have an NGINX reverse proxy serving the Admin interface behind SSL Client Certificate authentication on HTTPS port 443.

After updating my SSL certificates on the device with Lets Encrypt certificates, I started getting these errors in the syslogs, with a "Gateway Timeout" to the backend:

Sep 11 15:37:53 mgw pmgproxy[948]: Can't locate object method "set_request_host" via package "PMG::RESTEnvironment" at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 1206.

The admin panel no longer functions. Where should I start looking to debug this?

Same thing happens when going to the admin port directly.

[DISREGARD]

I was not up to date, I ran an upgrade via the command line to get everything up to date and it just started working again.
