I am trying to load CSV files to the DB on remote server, It starts loading few files and later it gives connect Timeout Exception

Tried setting the connection in metadata, it worked fine, Test connection was successful. In advanced setting added connectTimeout parameter. (Wanted to know whether it is in milliseconds or seconds) It loaded some 7 files and threw this error later

Hello,

Seems like the problem is not about the connectTimeout in additional params, but the refused connection from the server.

Can you try to put a tDBConnect to verify the connection is working well.

Once done, try to execute your job with tDBOutput with only one row to exclude the connection problem.

Regards

Are you using context variables for the credentials, try printing them out (maybe not the password) in the logs to verify it's using the correct credentials.

Has your remote server been whitelisted to access the database?
