# FiveM Database Connection Failed – Fix MySQL & oxmysql

FiveM "Database connection failed" or oxmysql error? MySQL/MariaDB connection, connection string, ESX/QBCore – database troubleshooting for RP servers.

**Quick answer:** "Database connection failed" = **wrong MySQL connection string** or DB unreachable. Check `mysql://user:pass@127.0.0.1:3306/dbname`, start oxmysql, import ESX/QBCore SQL.

**If you landed here:** FXServer starts but ESX/QBCore/oxmysql throws DB errors, players can't spawn or inventory empty.
