Hello experts,
We have setup our nifi to consume message from kafka broker which has SSL as security protocol.
It worked well with pre-prod brokers, but facing below error in prod broker.
(we have configured ssl context service with respective ssl certs)
Preprod nifi <-> Preprod kafka : working
Prod nifi <-> Prod kafka : Not working
telnet is working from Prod nifi to Prod kafka broker.

Any idea what could be the reason for this?
Thanks
