Problem connecting Database Replication module to MS SQL database

Hi all,  I am using the Database Replication module to connect to an MS SQL database. I have the Mx Model Reflection module installed and synced, as per the Database Replication module documentation. I have correctly added all the database details in the first 'Database' tab of the Replication Overview page, however when I click 'Sync the database' I am receiving the following error: "The TCP/IP connection to the host, port 1433 has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall."." I have checked my Firewall settings on my database and I have set a rule for all access to IPs -, but still no success. I have successfully connected to an MS SQL database using the Replication module before, so I'm not sure what's going on. Can anyone help with this? Thank you!

Does the host run in VPN? If so, you have to set up a VPN also to reach the DB-host
