not sure if this is nginx

8.3.14
- Is this the first time you’ve seen this error? (Yes / No):
Yes
- When did this problem seem to first start?
- Not sure, it happened after updating from NC 28 through the respective versions up to 30.0.3 and trying to fix some of the new issues (java .mjs MIME type for example)
- Installation method (e.g. AIO, NCP, Bare Metal/Archive, etc.)
LSIO docker container
- Are you using Cloudflare, mod_security, or similar? (Yes / No)
No
Summary of the issue you are facing:
After updating to a new Version and changing some (i think nginx config files) i only get a nginx 404 error. Sadly we lost power shortly after the change, and by now i have forgotten what exactly i did or at which step it occured.
Also, in my docker server setup, i have (amongs many other services) a nginx-reverse proxy running, but i don’t think it is this one that throws the 404 error. If you know how i can check if it’s the containers internal nginx or my own, please let me know 
I already tried recreating the container, also with new images, i tried deleting the nginx.conf file and letting it be recreated on container creation, to no evail.
Steps to replicate it:
Sadly, as mentioned, I don’t know exactly anymore
