Sophos XG Firewall Can't connect to the registration service

Hi,

does your ISP/rSP have open connections, maybe they run CGNAT which is blocking your access?

Ian

There is open and complete internet access. No restrictions were imposed.

XG650 - V19.5.3

Hi Derry Wang1 ,

Thank you for reaching out to the community, you can refer - Troubleshoot error: Can't connect to the registration service.

Resolution

• Make sure Sophos Firewall is correctly claimed on Sophos Central.
• Run fsck-on-nextboot on the device console.

If neither resolves the issue, proceed with the steps below:

1. On the Sophos Firewall CLI, go to 5. Device Management.
2. Select 3. Advanced Shell.
3. Run the command: cd /content/licensing
4. Run the command: ls
5. You will see the files lic_ csr.key and lic_csr.pem.
6. Remove both files by running the command: rm – rf
7. Once removed, try to register the Sophos Firewall again.
8. If you are still facing the issue, then please raise a technical support case.
