🐛 there are no free edge addresses left to resolve to

**Describe the bug**

Tunnel connector start failed with error: "there are no free edge addresses left to resolve to"

**To Reproduce**
Steps to reproduce the behavior:
1. Configure 'Follow the official website guide to create tunnel'
2. Run 'docker run cloudflare/cloudflared:latest tunnel --no-autoupdate run --token xxx'
3. See error: there are no free edge addresses left to resolve to

If it's an issue with Cloudflare Tunnel:
4. Tunnel ID : f045ed83-0fcb-4c7d-8c75-9fc74d6bd0d8
5. cloudflared config:

**Expected behavior**

I tried install the cloudflared with dpkg / docker / synology package.
I tried create tunnel with dashboard / cli command
I tried reboot the synology / router
I tried different version of cloudflared package.

But, I get this error every time.

The firewall on the synology is closed. I don't know what else I can do now.

I just hope it can normally run.

**Environment and versions**
- OS: Synology Nas, Linux
- Architecture: AMD64
- Version: 2023.8.1
