Glue Job Communications link failure, MariaDB

1

I was running glue job to process data from MariaDB inside VPC. Recently my glue job get "com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure" although it was running fine before. My preliminary research is this due to it cant connect to DB, but Glue Connection and Glue Crawler works fine, only when using job that it get the above error.

My theory is this issue is due to MariaDB auto update (minor versions). I'm stuck and couldn't find a solution. Any people using MariaDB experience the same?

Yes, I am also stuck and facing the same issue for last 10 days. When I am testing the Glue connection it is showing successful and crawler can crawl the data but Glue job fails with Communications link failure error.
