RAS error 651 The modem reported an error.
Previous firmwares used a 1024 bit self-signed certificate, and updating the firmware does not update the self-signed certificate automatically.
Modifying the certificate will update the SonicWall to a new 2048 bit certificate and will resolve this issue.
How to Test:
Browse to the SRA management interface.
Right click the lock in your browsers address bar to view the certificate.
On the "Details" tab scroll down and find "Public key" this field should contain "RSA (2048 Bits)" after the steps. (Above)
