Mysql: "The connection attempt failed because the connecting party did not respond properly after a period of time"

Question

I have a project using Asp Net MVC 4.5.2 and Mysql database. For a few days, my project started getting errors from Mysql. Everything is going smoothly in the project, but whenever I do some operations on Mysql workbench (like indexing or adding rows and .s to any table), my project immediately gets the following error from Mysql and that doesn't happen until Mysql restarts , everything goes wrong. After restarting, Mysql works normally again. I can't figure out where the problem is.

The first time I encountered the error was when indexing a table to speed up search queries. I thought the problem was with the index and undo it, but since that day the project immediately gives errors no matter what I do in Mysql.

The error message is always as follows:

"The connection attempt failed because the connected party did not respond properly after a period of time, or the established connection failed because the connected host did not respond"

Answer 1

The indexing you perform may cause excessive MySQL server resource usage, causing connection issues. Monitor the server's performance during operation in MySQL Workbench to see if there are any resource bottlenecks.

Check the MySQL server logs for any errors, warnings, or performance-related messages. The log is usually located in the MySQL data directory with a file name similar to error.log or slow-query.log. Analyzing the logs can provide valuable insights into any issues or resource bottlenecks the server may be experiencing.
