May I ask for your help. I’ve installed Openfire 4.4.2 and MySQL 8.0.18 in Ubuntu 16.04. The problem is, I cannot import the database in GUI. It always says:
“A connection to the database could not be made. View the error message by opening the “/logs/error.log” log file, then go back to fix the problem.”
Database URL: jdbc:mysql://127.0.0.1:3306/sparksdb?rewriteBatchedStatements=true
I also tried the localhost, servername and server IP, but still error appear.
