When using Windows 7 as a node for a portal, you may sometimes need to update your TLS 1.2/SSL for it to function properly.
NOTE!
Even if TLS 1.2 is listed, it might still need an update.
You can check the TLS version by pressing the flag (Windows key), selecting Run, and typing inetcpl.cpl. Navigate to the Advanced tab, scroll down to Security, and you should see “Use TLS 1.2”. Even if this is listed, it might need to be updated if you receive the error message:
“The request was aborted: Could not create SSL/TLS secure channel.”
This message usually appears in the debug log when HttpClient, WebRequest, or similar classes fail to negotiate a secure connection with the server.
To view this error in the debug log, you must enable the node connection in debug mode under Node Setup.
