OnePlus n10 5g, magisk 23.0 oos (android 11) - just upgraded to new Nethunter app

Error in the Chroot download.

Error in the Chroot download, possible causes: server down or conection issues, here is the error: No valid pins found in chain!

Error received when using the newest Nethunter chroot app... (Reason for reinstallation was recieving error when trying to upgrade and update- some error like unable to resolve source dist something- where as it apt update && apt upgrade fine before) so full chroot uninstallation and upgraded Nethunter chroot app and now this error as shown above.. any ideas or help would be greatly appreciated

Thank you in advance
