When installing any operator via OperatorHub, the install hangs and never completes. The follow error is given:

~~~

Tried to uninstall and delete the operators and then tried to install it but the operator remain in unknown state. Even tried to install it in single namespace but that did not work.

Some operators install but it takes very long time to install while some operators remain in unknown state.

The operator should be installed quickly without any errors.
