Timeout Expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

Solution

Take a backup of Registry and do as follows. 

1. Open registry editor. 

2. Go to the following directory path to navigate to the registry key:

“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters” 

3. Look for the TcpTimedWaitDelay key name. If not found, add it by selecting Edit > New > DWORD Value from the menu bar. Rename the key name to “TcpTimedWaitDelay”. 

4. Double-click inside the right pane again to set the value of TcpTimedWaitDelay. Select Decimal as the Base, and enter 30 in the Value data field. 

5. Look the MaxUserPort key name. If not found, add it by selecting Edit > New > DWORD Value from the menu bar named “MaxUserPort”. Set its value to a decimal value between 5000 and 65534

DWORD - MaxUserPort - 65534

6. You must restart Windows for these settings to take effect.
