Keep getting an error about not being able to sync with Anki Hub when I open Anki

When I log into Anki, I keep getting this error message about it not being able to sync to Anki Hub. I included the error details below. Please let me know if you can help with this error. Also, should I still do my cards today or should I wait until the error resolves to do cards again?
