generative fill isuues no internet connction

When I try to use the generative fill feature, I receive an error message stating there is no internet connection. This is puzzling because my desktop computer is indeed connected to the internet. I'm looking for guidance on how to troubleshoot this problem. Specifically, I would appreciate insights into potential causes for this discrepancy between the error message and my computer's actual internet status, and suggestions for steps I can take to resolve the issue.
