Motioneye access to Google Drive or Dropbox

Hi,

I was trying to use motioneye to access Google Drive to save the video recordings, but it failed.

After I clicked “Obtain Key”, it showed me below

As for Dropbox, it was stuck in this state after I got the key and clicked the “Test Service”.

Is there any solution or missing for this issue or is it better to use FTP or SFTP server to save data?
Is there another app easier to use than motioneye?

Thanks!

I have the same error when I try to get authorization key.
