nginx Error 502 After Upgrade to 4.2.2 (uWSGI fix)

[ceyounger]

I followed the instructions for upgrading to Netbox 4.2.2 and after upgrading I started getting HTTP 502s from nginx after the upgrade.

I use uWSGI not Gunicorn.

After a lot of stumbing around, I found I needed to increase the buffers in the uWSGI.ini like so:

; uWGSI Buffer (default=4096)
buffer-size = 32768

I was seeing these errors in the log which led me to this:

2025-01-23T20:33:43.045276+00:00 XXX uwsgi[3190]: invalid request block size: 4923 (max 4096)...skip
2025-01-23T20:33:43.209920+00:00 XXX uwsgi[3190]: invalid request block size: 4856 (max 4096)...skip

Hope this helps someone!
