Hi,

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

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:

On the Sophos Firewall CLI, go to 5. Device Management.

Select 3. Advanced Shell.

Run the command: cd /content/licensing

Run the command: ls

You will see the files lic_ csr.key and lic_csr.pem.

Remove both files by running the command: rm – rf

Once removed, try to register the Sophos Firewall again.

If you are still facing the issue, then please raise a technical support case.
Thanks & Regards,
