Thank you for this suggestion. We followed the below steps to resolve it.
1. start the evm agents
2. Opened the configure page of grid manager platform
3. Cleared all the fields which includes the lsf admin username, passwords, ticket url and service url
4. Saved the changes
5. Then stopped the evm agents and waited for the metadata server to unlock the account which took 5 minutes
6. Started the agents and then updated the fields
This seemed to have worked.
