It seems like you're encountering an issue where a connection is established with the server, but then something goes wrong. This type of error can occur due to various reasons, such as:
1. Timeouts: The connection might be taking too long to respond, leading to a timeout error.
2. Network Issues: There could be network disruptions or firewall issues disrupting the connection.
3. Server Configuration: Improper server configuration or limitations on the server side could cause the connection to fail after being established.
4. Server Load: High server load or resource constraints can cause connections to drop unexpectedly.
5. Software Bugs: Bugs in the application or server software could lead to connection issues.
To troubleshoot this error, you can:
- Check the server logs for any specific error messages or warnings that could provide more insight into the issue.
- Verify the network connection to ensure there are no intermittent disruptions.
- Review the code that establishes the connection to see if there are any issues in how it's being handled.
- Test the server with different loads to see if the error is related to high server traffic.
