How to Fix: Unable to access github, getting ERR_SSL_PROTOCOL_ERROR error
GitHub SSL connection error on Win 7 Professional
📋 Table of Contents
The ERR_SSL_PROTOCOL_ERROR error occurs when your device is unable to establish a secure connection with GitHub's servers. This issue affects users who access GitHub from their office or any other location, and it can be frustrating as it prevents you from accessing your repositories.
This error can also occur due to various reasons such as the server being down or requiring client authentication certificates that are not available. In this troubleshooting guide, we will walk you through the steps to resolve this issue.
🔍 Why This Happens
- The primary reason for this error is the detection of an outdated SSL protocol version by your browser. GitHub uses a secure connection (HTTPS) to protect its users' data, and if your browser detects an outdated protocol version, it will throw an ERR_SSL_PROTOCOL_ERROR error.
- Another possible cause is that your LAN settings are set to use an outdated or incompatible protocol version, which can also lead to this error.
✅ Best Solutions to Fix It
