Error during creation of site-to-site connection

Hi,

I am setting up a site-to-site VPN with the new resource manager, following this step-by-step guide:

https://blogs.technet.microsoft.com/keithmayer/2015/12/22/7-steps-to-building-site-to-site-vpn-connections-for-v2-vnets-using-azure-resource-manager-in-the-new-azure-portal/

During step 6 I get this error:

• DESCRIPTION
  Failed to create connection 'test'. Error: An error occured.
• STATUS
  Error
• TIME

I setup another site-to-site VPN last week using the same guide, and it is working without any problems.

Any advice on how to proceed or how to fix this issue?
