Issue with artifact upload

Hi, I have gitlab CE 18.3.2 installation running and runners running version 18.3.1. I have an issue with uploading artifacts. Uploading of artifacts is failing with ERROR: Uploading artifacts as
```
“archive” to coordinator… 413 Request Entity Too Large correlation_id=238dfdd1bd4c460f9ebe8c4c752691bc id=1146169 responseStatus=413 Request Entity Too Large status=413 token=64_sEPwoX

FATAL: too large
```
Already nginx client_max_body_size is set to 0 and on admin area, maximum artifacts size is set to 6GB which is the max size of artifacts required.

still, it is not working. doesn’t know what is causing the issue. Another interesting fact, the job is passing when the artifact is less than 3GB while when it is greater than 3GB it is failing
