Hi, @Kamil Krauze (Student) Welcome to the Microsoft Q&A platform, thanks for posting the question
I understand you are facing an issue while trying to connect the Azure Mysql server from the Mysql workbench.
- Are you connecting from Azure (like Azure VM etc) or outside Azure?
- Are you able to connect using MySQL command line client or mysql.exe? for your reference Connect to the server by using mysql.exe
- Did you checked if the public IP of the client where your workbench is installed is whitelisted in em-nonprod-mysql-server-flex server? Firewalls prevent all access to your database server until you specify which computers have permission. The firewall grants access to the server based on the originating IP address of each request. To configure a firewall, create firewall rules that specify ranges of acceptable IP addresses. You can create firewall rules at the server level.
