HELP! Endnote X9.3.1 on Mac reporting "A 'sync' error has occured(200)"

I encountered this problem months ago, I referred to 

https://community.endnote.com/t5/EndNote-How-To/Endnote-X9-quot-Sync-quot-error/td-p/151272

which says it is because server error, so I waited and it went ok after a day or two.

I encountered the same problem weeks ago again, I thought it was the server error again and would be ok after a few days, BUT IT DOES NOT this time... I found the error message is still there today, then I update endnote from X9.2 to X9.3.1, but the error is still there. 

 

I can use endnote on Windows and iPad smoothly, but there is the weird sync error on Mac...I cannot sync the library, nor can I try to sign in again in the software, it seems every time I want to connect to the server, "A 'sync' error has occured(200)" appears.

 

PLEASE HELP....TwT

 

Here is the Sync status:

Ohhh..It seems that endnote cannot work with Latern VPN running in the background, when I quit Latern, endnote works smoothly.
