Problem: In LDMS, when on the Manage Cloud Services Appliances, error "Failed to save the CSA settings" pops up. The password field on this screen also appears blank. Usually seen after an upgrade (ie, 95 to 9.6, etc)
Explanation: Database table was corrupted.
Solution: Delete that existing CSA reference line in the database, not LDMS.
To do this, login to the database and run this query:
select * from brokerconfig
You'll now see the CSAs you have configured in LDMS. Find the one that's not letting you save the changes and make note of the BrokerConfig_Idn number.
Then need to run this query:
delete from BrokerConfig where BrokerConfig_Idn = ? (replacing the question mark with the number you noted before)
After this completes, update the client connectivity settings in your agents.
