Computer geeks are experts from dealing with such issues, but an average computer user may find it difficult to repair. The error will occur on your device when you are using the ‘HttpWebRequest’ class to retrieve an image from another server.
How Can You Resolve the Issue?

Method1: Disable KeepAlive

The error is related to programming issues, so disabling the ‘KeepAlive’ feature can help in getting rid of the error. The error may occur because the.NET’ framework platform closes the connection without finishing the desired action. Disabling ‘KeepAlive’ feature can help in closing the connection after every request gets completed. You can browse the web to find some self-help tutorials that can assist you while disabling the feature.

Method2: Set ProtocolVersion to Version10

You can apply this method to set the ‘ProtocolVersion’ to ‘Version10.’ Making changes in the ‘ProtocolVersion’ forces the ‘HTTP request’ to use ‘HTTP 1.0’ and thus resolves the issue instantly. If you’re not a tech geek and don’t know much about changing versions of the protocol, then try taking help of a PC repair technician.

Method3: Limiting the Number of Service Points

Setting the ‘ConnectionLimit’ property to the maximum number of connections can help in resolving the issue. Making changes in the property will help in increasing the number of connections that the ServicePoint object can create to access an Internet resource. Microsoft recommendations state that the ‘ConnectionLimit’ should be set at ‘12’ connections per CPU, but you can increase it to more connections, depending upon the network bandwidth.
