@PaulR282 Are you using netbox-docker by chance?

We went through the same thing. It's not a NetBox issue, it's a web server setting in the docker config. You need to add this setting to the docker/nginx-unit.json file.

"settings": {
  "http": {
    "max_body_size": <int in bytes>
  }
}

Then you need to rebuild the container and have the file copied over. We did something like this in the Dockerfile:

COPY docker/nginx-unit.json /etc/unit/

That's been working for us nicely.
