glue connection not working to crawl DB table

Hi team,

I have 2 glue crawlers :

• 1 in dev account that crawls database tables from aurora serverless MYSQL
• 1 in stg account that crawls database tables from RDS aurora MYSQL 8 version: AuroraMysqlEngineVersion.of("8.0.mysql_aurora.3.01.0", "8.0")

I created a glue connection to connect to my RDS aurora MySQL and crawl my DB tables. The connection in dev (serverless aurora) works fine and tables are crawled, but it doesn't work in stg (MYSQL 8) :

Check that your connection definition references your JDBC database with correct URL syntax, username, and password. Could not create connection to database server.
10:34
Exiting with error code 30

and when I run the crawler it fails telling that: fails to connect to the database

when creating the connection in stg I tried both types : JDBC and amazon Mysql Aurora non of them want connect to the DB

my JDBC URL looks like this in both accounts dev and stg :

mysql://databasestack-databaseb2sdgfbb-128ewdfsdsi3ew.cluster-csdggdsf1qdsdgdfc.region.rds.amazonaws.com:3306/myaccountdb?verifyServerCertificate=false&useSSL=true

not sure what is the issue here in stg account, how can I make my crawler/connection work two be able to crawl my tables on the database ?

Thank you!!!
