However, quite recently, a lot of reports have been coming in of an “an existing connection was forcibly closed by the remote host” error while trying to connect to the remote host. This error is triggered with a socket connection between a client and a server. In this article, we will provide some viable solutions to completely rectify this error and also inform you of the reasons that trigger this error.
What Causes the ‘An existing connection was forcibly closed by the remote host’ Error in Windows?
After receiving numerous reports from multiple users, we decided to investigate the issue and devised a set of solutions to fix it. Also, we looked into the reasons due to which it is triggered and listed them below. Now that you have a basic understanding of the nature of the problem, we will move on towards the solutions. Make sure to implement these in the specific order in which they are presented to avoid conflicts.
Solution 1: Enabling Cryptography
If Cryptography has been disabled for your machine the usage of TLS 1.2 is prohibited. Therefore, in this step, we will be enabling Cryptography. For that:
Solution 2: Forcing TLS 1.2 Usage
If the application has been configured to use TLS 1.1 or TLS 1.0 instead of the TLS 1.2, it might trigger this error. Therefore, in this step, we will be configuring our computer to use TLS 1.2. For that:
Solution 3: Changing Socket Implementation
If a certain socket implementation has a bug or glitch in it, it might prevent certain elements of the application from functioning properly due to which this error might be triggered. Therefore, in this step, we will be configuring it to use a different implementation. For that:
Solution 4: Adding Command Lines (Only for Entity Framework)
If you are using the Entity Framework, it is possible that a certain line of code might be missing. Therefore, in this step, we will be adding that line of code in order to fix this issue. For that:
Solution 5: Updating .NET Framework
The latest version of the “.NET” Framework is required in order for everything to function smoothly. Therefore, in this step, we will be downloading the latest version from the site and installing it. For that:
