OOO: Server is not Reachable

Problem:

The message “Server is not Reachable” is displayed on your BATM.

Other BATMs in your network do not display this message.

The underlying cause of this type problem may arise in one of these five areas:

This article describes possible solutions at the BATM side of this graphic.

Obviously, we cannot control the Internet or your routing - but you may want to check CAS if you run your own server and ALL your BATMs are offline:

Master Service Issues

We recommend Ethernet in areas that have weak or unstable Internet access.

Some WiFi routers just aren’t up to the task. A strong WiFi signal doesn’t mean a stable connection. A microwave oven or various electronics may generate spurious signals that disrupt the connection - and cause this error. Ethernet overcomes this weakness.

If Ethernet is not an option in your case, consider improving the WiFi connection:

Solutions:

Ensure that you are connected to a local router.

Configure Wi-Fi, or better yet: connect using Ethernet.
Confirm that an IP is assigned in your Administration screen.

Confirm that your router can access the Internet.

Connect your phone or a laptop computer to the router & test access.
Ethernet: ensure your router is NOT set to rate auto-negotiation.

Disable unused Wi-Fi connections.

Finally, check that the Server IP is properly set.

The server will definitely be unreachable if the BATM is “dialing” the wrong IP, or is unpaired with CAS.

The Server IP is set to a GB default.
The Server IP may reset to the default after certain BATM procedures.

Make sure the BATM is paired with your CAS: Error: TLS error
