Like the other post I seen I am getting:
Can't reach database server or port
SQLState - 08S01
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
We have verified the network and all the DB settings but getting the same message.
This is with:
confluence 8.5.8 64bin Ubuntu installer
mysql Ver 8.0.15 for Linux
mysql-connector-java-8.1.0.jar driver.
