VPN connection to apsdemo does not work. Connection hangs for a while and then fails. Log of the connection contains TLS error similar to this one:

TLS Error: TLS key negotiation failed to occur within 60 seconds
TLS Error: TLS handshake failed


Problem with VPN certificate.


Go to your profile on and request a new VPN certificate (you may need to revoke your existing one first).

The new certificate should be available shortly (in about 5 minutes or sooner).

Download the new certificate and configure your VPN connection to use it.

If that still does not work, there may be problems on the remote side (on the side of VPN infrastructure) at that time. Please submit a request to the APS Developer Support (make sure to include VPN logs and any other relevant infromation in your request).
