Error "Host's UUID does not match expected UUID for that host ID"

Yes

Question:

What is the error "Host's UUID does not match expected UUID for that host ID" means while trying to activate Licenses on Local License Server (LLS) from FlexNet Operations.

Answer:

"The UUID is generated by FNO when a device first sends a capability request and that UUID is then stored in the TS and used as an identifier each time there is a request". This means if at any point of time, the UUID information at client changes it will not match with the information present in server TS or vice versa and the error "Host's UUID does not match expected UUID for that host ID" will be thrown.

So for troubleshooting one can follow below.
1)To check if unique identifier or hostid information either at server(FNO) or client got changed.
2)Obsolete Device/LLS in FNO and Delete TS at client/LLS and recreate them.
