Issue occurred when attempting to access the data explorer. It appears intermittently. But, once it occurs, you lose access to the data explorer entirely. Cannot hard refresh the page to recover.

I did a little more testing this AM. Once this occurs, opening an incognito session allows access to the data explorer. After this, I went back and cleared my cache and cookies out of Chrome, and that also allowed me to access the data explorer again.
