How to Fix: netsh "Error: 87 The parameter is incorrect" when using hostnameport

The 'netsh http add sslcert hostnameport' command is used to create an SSL certificate for a specific hostname and port. However, when using this command, users may encounter the error 'Error: 87 The parameter is incorrect'. This error typically affects Windows systems running the latest versions of the netsh command, which may be due to changes in the way the command interprets the 'hostnameport' parameter.

This error can be frustrating for users who are familiar with using the 'ipport' parameter and have successfully created SSL certificates using this method. However, switching to the 'hostnameport' parameter can resolve compatibility issues between older and newer versions of Windows.

🔍 Why This Happens

• The primary reason for this error is that the 'hostnameport' parameter requires a specific format, which may not be met by users who are unfamiliar with this syntax. The correct format for the 'hostnameport' parameter includes the hostname followed by the port number separated by a colon.
• Another possible cause of this error could be the version of Windows being used. If the user is running an older version of Windows, it may not support the 'hostnameport' parameter, resulting in this error.

🚀 How to Resolve This Issue

💡 Conclusion

To troubleshoot the 'netsh http add sslcert hostnameport' error, verify the format of the hostname and port number. If using an older version of Windows, consider updating to a newer version for better compatibility. Alternatively, try using the 'ipport' parameter instead. By following these steps, users can resolve this issue and successfully create SSL certificates.
