I installed the Jaspersoft Studio community edition and then created the Data Adapter, JDBC Driver --> com.mysql.jdbc.Driver, JDBC url --> jdbc:mysql://nofrg.eu/gsf650s_nofrG, and username and password. The Data Adapter does not work and the message is “Access denied for user gsf650s_vlks@212.22.33.9. Τhis address (212.22.33.9) belongs to my router and of course there is no such user in the database gsf650s_nofrG. I would appreciate your help
