Unable to connect to repository

Hi Everyone,

I have a load error due to missing node extensions for SAP r3 RFC downloader, upon trying to search and install for required extension this error appears “Could not query updates site for missing extensions. Unable to connect to repository i.e https://knimeserver.pg.com/knime_installer/update5.2/content.xml” then Connection timed out: no further information. Any insights for the solution for this problem?

Any help and ideas you could offer would be very appreciated. Thank you.

Best Regards,
