Error: The operation was aborted because the client side timeout limit was exceeded.
Description: Let’s take an example, here the client side we will refer to Active Directory. The Active Directory module imposes a two-minute operations timeout. When the timeout reached, the connection will be dropped and server will return operation timeout error message like “Ldap operation timeout”. This might happen due to slow network connection or the Active directory querying results are not returned within the two minutes. This can be happened with any database queries also.
- Check the network connectivity between the host and client.
- Make sure the server’s are accessible or not.
- Check the timeout settings.
Error: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 – The semaphore timeout period has expired.)
Description: Again this error occurred due to slow network connection or bad network configuration. For example, when we try to connect a SQL Server through application, and the request taking so much for the output. The networking layers will bubble this error to SQL Server which will present to us as provider: TCP Provider, error: 0 – The semaphore timeout period has expired.
Solution: Nothing related to code logic, just check the network connections are working properly or the server is up and running. Contact your Network Administrator.
