I have been using Binance with a VPN for 2 Years and I have not encountered any problems, but I can summarize the reasons for your problem as follows:

 - you are using a free VPN, which may be prohibited by the platform.
 - Connecting from US VPN address.

To avoid problems, try the following:

 - Purchase a dedicated VPN address.
 - Avoid contacting VPN addresses from the United States.
 - Try to use the same country every time.
 - remove cookies and edit your local time.
