For the last 2 days, I have been unable to use the Opening Explorer reliably. I am always authenticated, and have been persistently seeing the error:

Oops, sorry!
TypeError: NetworkError when attempting to fetch resource.

Is this related? How can I resolve this?

All the other resources (playing games, puzzles, viewing public studies, etc.) are working for me. Only the Opening Explorer has been broken. Screenshot shows I am authenticated.

After I cleared all history, cache, site settings, everything, then logged out and back in, the Opening Explorer is working for me again. Thank you.
