The yml I use here

At first I thought it was a problem with the driver and connection pool versions, but later I changed them all to the latest versions and still got the same error.

Solution

Finally, I found a problem with the time format that was originally put back. The time was 8 hours faster. Finally, I added serverTimeZone=GMT after the application configuration url and the problem was solved.
