Failed to authenticate request

I have cancan downloaded and built. It launches and is functional throughout authenticating with the Dfinity internet computer, but I get an error whenever I try to navigate through the app or take and action.

It reads:

Unhandled Rejection (Error): Server returned an error:

Did I miss something? What do I need to do to make sure that requests are authenticated?

I can’t seem to get CanCan to launch, does it need to have Internet Identity running locally?

I just followed the instructions on the GitHub repo.

A couple issues I had - vessel didn’t download to my $PATH, so I had to find that and move it to the $PATH.

Also, make sure you hit the /sign-up route.

For now, yes. See https://github.com/dfinity/cancan/blob/main/docs/local-with-internet-identity.md for instructions.
