After installing a new UF, why is it not forwarding logs to the Indexers?

05-10-2018 15:13:13.954 +0000 ERROR TcpOutputProc - Error initializing SSL context - invalid sslCertPath for server 45.125.XXX.X:9997 05-10-2018 15:13:13.959 +0000 ERROR SSLCommon - Can't read key file /opt/splunkforwarder/etc/auth/server.pem errno=151429224 error:0906A068:PEM routines:PEM_do_header:bad password read. I just installed a new UF but it's not forwarding logs to the Indexers and the $SPLUNKHOME /var/log/splunk/splunkd.log shows the error message above. The IP in the error message is that of the Indexer: It is connecting to the Deployment Server and getting configs but not sending logs to the Indexers. I need help understanding what is happening. I have reinstalled the UF but still got the same error messages. The certs are default Splunk certs Thanks
