Same here, and clicking the Try Again button makes it render but we need it to render as normal on the 1st attempt
We are also facing the same issue.We are using the Postgres SQL server. as mentioned by BRAIN by clicking the try again button makes the view render.
We are getting this same error as well. I am an admin, and never get the error, but some of our accounts that are set to interactor get that error for small periods of time (30 minutes to a few hours). I have not found a solution yet. The try again button doesn't work. Logging out and back in doesn't fix it.
Since nobody has given a solution I would recommend contacting Tableau Support. Please post the solution here
