Cannot Connect to Shiny Account When Publishing

I'm trying to publish a flexdashboard. When I try to publish all the documents in my folder (as opposed to publishing only the current document), I run into problems connecting my account to rstudio. When I enter my rsconnect string (the string with the token and secret), R studio seems to go through the motions of connecting my account. But, it never does.

Has anyone else run into this kind of connection problem? This does not happen with my other Shiny apps. So this makes me wonder if I just don't understand how to publish a dashboard with flexdashboard.

Thanks in advance for the community's help and advice.
