HTTPS traffic 40x slower than HTTP in Windows 10 x64

answer to a question regarding HTTPS traffic running slower than HTTP traffic in Windows 10.

The issue of HTTPS traffic running slower than HTTP traffic in Windows 10 is an issue that has faced many users. While this issue can be caused by a variety of factors, there are several steps you can take as an IT admin to troubleshoot and resolve it.

The first step is to check the Network Adapter settings. In the Control Panel, navigate to the Network and Sharing Center and then to the Change Adapter Settings. Right click on the Network Adapter and select Properties. Make sure that the appropriate check boxes are ticked for Internet Protocol Version 4 (TCP/IPv4) and Internet Protocol Version 6 (TCP/IPv6).

The next step is to check the security settings for the Network Adapter. Open the Security tab, and make sure the appropriate check boxes are ticked for the Allow encryption types of 40-bit, 56-bit and 128-bit. This will ensure that the encryption types are enabled and can support HTTPS traffic.

The third step is to check the settings for the router. Log into the router and check its settings. Make sure that the router is configured to allow HTTPS traffic. This can usually be done by setting the router to allow traffic on port 443. It is also important to check the router’s firewalls and make sure that they are not blocking traffic on port 443.

The fourth step is to check the settings for the browser. Make sure that the browser is set to allow HTTPS traffic. This can usually be done by checking the settings for the browser and enabling the use of HTTPS.

The fifth step is to check the settings for the operating system. Open the Windows Firewall and check the settings. Make sure that the firewall is configured to allow traffic on port 443. It is also important to check the settings for the Windows Defender and make sure that it is not blocking traffic on port 443.

Finally, if all of the above steps have been completed and the issue persists, it may be necessary to contact the Internet Service Provider (ISP) and inquire about any possible issues with the connection. It is also possible that the issue could be caused by a third-party application or service. If this is the case, the application or service should be disabled and the issue should be resolved.

By following the steps outlined above, an IT admin should be able to troubleshoot and resolve the issue of HTTPS traffic running slower than HTTP traffic in Windows 10. While this issue can be caused by a variety of factors, the steps outlined above should help to identify the cause of the issue and resolve it.
