Describe the bug

Yesterday, I tried changing the network mode of NginxProxyManager from bridge to host. Today, when I checked the monitoring, I was surprised to find that it had been wasting download traffic the whole day, repeatedly fetching something from Cloudflare (server-54-192-18-106.hkg62.r.cloudfront.net, ip-ranges.amazonaws.com). It used up 40GB of traffic in one day.

I realized that the issue might have been caused by switching to the host network, so I changed it back to the bridge network, and the problem disappeared.

Nginx Proxy Manager Version

v2.12.2

To Reproduce
Steps to reproduce the behavior:

• I'm not sure how to reproduce this issue, because when I checked another PVE server using the host network, I didn't find this bug.
