Why is there connectivity issue in the UF after upgrading?

Hi Team,

After upgrading the SSL certificate we are not able to connect to Deployment server from UF. we are getting the below error logs.

DC:DeploymentClient - channel=tenantService/handshake Will retry sending handshake message to DS; err=not_connected
INFO DC:PhonehomeThread - Attempted handshake 1050 times. Will try to re-subscribe to handshake reply
 INFO DC:DeploymentClient - channel=tenantService/handshake Will retry sending handshake message to DS; err=not_connected
 WARN TcpOutputProc - The TCP output processor has paused the data flow. Forwarding to output group primary_indexers has been blocked for 12600 seconds. This will probably stall the data flow towards indexing and other network outputs. Review the receiving system's health in the Splunk Monitoring Console. It is probably not accepting data.
 INFO DC:DeploymentClient - channel=tenantService/handshake Will retry sending handshake message to DS; err=not_connected

Try and check DS logs and see if you can find an error related to ssl for that forwarder this will confirm its due to ssl.
