What is the strange problem with OpenLiteSpeed and Redis Object Cache?

#1
I have three websites on one vps. Use OpenLiteSpeed.
I separated the username of OpenLiteSpeed’s PHP.

Code:

PHP user A, PHP user B, PHP user C.
However, the plugin Redis Object Cache for PHP users C appears “Permission denied”
The other two websites are intact. What is the reason for this..
The configurations of the three websites are the same

the plugin Redis Object Cache for PHP users, Do you mean LSCWP plugin object cache settings?

users C appears “Permission denied”, Can you show more details from the error log for what kind of permission issue.
