"There was an error retrieving files!" happens

[kjmatsuda]

Hi!
From about two month ago, when I open org-web(https://org-web.org/), I get the message "There was an error retrieving files!" and no file lists show up.

In June 21, I deleted cookies and login in the morning, I can render file lists. At night of the day, I open org-web again, then the error above shows up.

I use Dropbox as a backend service.
Do you come up with some solution?
With some hints, I might be able to fix this.

Thank you,

Similar problem happens in organice.

Dropbox seems to change policy of manage tokens.
I will check it out.

Sorry, this is beyond my knowledge. I close this.
