Hi @33151609
Thanks for posting your query in Q&A platform.
I’m sorry to hear about the intermittent connection issues you’ve been facing with your MySQL Flexible Server. I understand how disruptive this can be, especially when it’s affecting multiple tools like Power BI, Synapse pipelines, and your front-end applications.
It’s good that you’ve already tried rebooting the server, but since the issue persists across all connections, it might indicate a deeper problem. Here are a few suggestions that could help resolve the issue:
- Sometimes, service disruptions can occur at the regional level. Have you checked the Azure Service Health dashboard to ensure there are no ongoing issues in your region?
- Since all tools are affected, there could be a network-related issue. Please review your network configurations to ensure there aren’t any firewall or DNS problems affecting the connection to the MySQL Flexible Server.
- I recommend enabling diagnostic logging for your MySQL server. This should provide more details on any errors that may be occurring under the hood.
- The error in your Synapse pipeline suggests there might be a connection timeout issue. It could help to review and adjust your connection timeout settings for both Synapse and Power BI to ensure they can handle larger or longer-running queries.
- Sometimes, high resource utilization on the server can lead to intermittent failures. It might be worth checking if your server needs scaling to handle the current load.
I hope these steps provide some direction, but if the issue continues, I’d recommend reaching out to Azure Support for further assistance. Please let me know if you need any more details..
