Queries take too long after MySQL fail-over

I have an application that uses MySQL fail-over via a connection url:

jdbc:mysql://172.17.0.4:3306,172.17.0.3:3306/db_name?autoReconnect=true&failOverReadOnly=false 

Now when primary db is down then it should move to secondary connection and application flow should work as expected.

Now the problem happens when moving to secondary db. It takes too long to move/execute the queries, causing the flow to take much longer than expected.

I have checked already with db and there's no slow query issues. I guess it's something to do with fail-over and with checking the states. So, any idea what might be causing this issue or how to resolve this delay?

I am also using c3p0 to manage the connections pools. Already tried with initialTimeout and maxReconnects but no luck so far.
