Error saving a pdf to document cloud

Re: Unknown error saving a pdf to document cloud

I have the same problem and it is one year later.

Whether I click the icon or use CTRL SHIFT W to upload to Document Cloud, I sometimes receive a message in the lower right corner reading, "An error occurred while trying to access the server."

I logged out and re-logged in.  I re-booted my computer.  I waiting a day and tried again.  Still nothing.

I retrieve my documents initially logged into my laptop, but I like to upload to document cloud so I can read them on my iPad and not be tied down to my laptop.

I'd appreciate a substantive response.
