Self-Hosted: Access to admin but not to projects

Hi everyone,

We use for more than 4 years gitlab self hosted on a Linux distribution with not Nginx bundled without a problem.
This morning, I do the update to the 14.2.1 and the problems begin… I have access to the admin area but not to the Projects (502 error).
I verified the path to workhorse socket and update the permission for the external user (I had problem with some permissions).

Does anyone have the same (weird) issue?

nginx version: nginx/1.19.6
