Error while validating the JWT token. Reason: invalid signature

Ready to post? :mag: First, try searching for your answer.
I connected an application to Auth0 and everything worked fine for a few weeks. But now, when try to log-in to my application using Chrome I get “Error while validating the JWT token. Reason: invalid signature”.
This happened to several users, so it’s not local my computer. I can resolve by deleting cookies, but I want to avoid the situation. Any ideas what might be causing this and how to resolve?
