Environment

Release : 10.x

Resolution

1. Try to delete l7-config folder under opt/SecureSpan/platform and REBOOT GW machine. The folder will be rebuilt once the reboot is finished.

Make sure you have a snapshot/back up of the API GW and also have a back up of the l7config folder, in case something goes wrong.

OR

2. Please check if there is a discrepancy in the location of the com.l7tech configuration files plays a role in this problem.
The machine they are experiencing the problem is the only one where there is a l7-config directory in the path twice:

In this case, please try renaming the parent l7-config folder first, move the child folder under /Platform and try to use the restricted shell now
