Common reasons for database connection timeouts include network latency, server overload, insufficient database resources, incorrect connection configurations, and firewall or security group settings that block the connection.
For example, if a web application is trying to connect to a database server located in a different geographic region, network latency can cause the connection to time out. Similarly, if the database server is experiencing a high volume of requests, it may become overloaded and unable to respond to new connection requests in a timely manner.
To mitigate these issues, organizations can use cloud-based solutions such as Tencent Cloud's Cloud Database services, which offer high availability, scalability, and fault tolerance features to ensure reliable database connections. Additionally, optimizing connection pool settings, configuring firewall rules to allow database traffic, and monitoring database performance can help prevent connection timeouts.
