Splunk DB Connect 3 Connection Failure MS SQL Server

[santoshkrishna]

Hi ,
I have a MS SQL database from which i need to pull some logs.
I installed DB connect 3 (both 3.1.1 and 3.1.3) added the correct drivers, identities.
i am able to connect to the database and pull the data from the SQL query explorer. But when i try to schedule the inputs to run a cron job and save the data to an index. It fails with the following error:

2018-07-16 12:30:09.071 -0400 [QuartzScheduler_Worker-1] ERROR org.easybatch.core.job.BatchJob - Unable to write records

But when i switch back to splunk db connect 2(2.4.2) i don`t have any issues and i can see that the connection was successful. Is this an error in db connect 3 app or am i missing something.

Found the Issue.It was a port conflict.
Apparently we had another application that was trying to use the same port(8088) for writing events into splunk. We changed the HEC port to 8188 and that fixed the issue for us.
