Allow Dropbox Access failure

yesterday installed erpnext on a digital ocean dropbox. Installation was smooth but Allow dropbox access is not working. Seems like dropbox api v2 is not allowing http links… Any idea how to solve it?

If the site is public you may want to move to https?

For example with each Chrome upgrade Google is promoting SSL and warning against non-SSL sites

Any option without moving to https? Few people within our company use erpnext deployed on digitalocean. So no plans to move to https. Any other workaround?

Maybe look into sftp or possibly someone else has a suggestion or experience?

Both ends seem to claim support
