For the DoodleMaths app to connect to our servers and retrieve children’s work programs, like any other application it needs to be allowed through the school network firewall. In addition, if it is installed on a PC, it will also need to be allowed through the PC's Windows Firewall, and possibly even another installed firewall such as AVG, McAfee, Norton etc.

It’s extremely rare for us to have a server issue: we have two load-balanced servers, based in the UK. If there’s an issue on one, traffic is instantly diverted to the other to ensure there’s no service interruption. If you are having connectivity issues, it’s much more likely to be a network/firewall issue.

Troubleshooting firewall issues:

  1. Bypass the school network by tethering the PC to a 4G hotspot on a phone. If DoodleMaths connects via the hotspot but not the school network, it’s the school network firewall that is the problem.
  2. If, in a school, some devices connect (usually iPads) but others don’t (usually PCs), this indicates a firewall issue on the PCs - either Windows Firewall or another installed firewall is not allowing it through.

Fixing firewall issues:

  1. If it’s a school network issue, try the following: whitelist the following domains:

as well as ensuing ports 80 and 443 are unblocked for the DoodleMaths app.

  1. If it’s an issue with the Windows Firewall on the PC, you will need to change the settings on the firewall to allow DoodleMaths through. For Windows 8 and 10, you’ll need to go to Control Panel > System and Security > Windows Firewall > Allow an app or feature through Windows Firewall > Select “DoodleMaths”

Since all school networks are configured differently, it’s very difficult for us to support firewall issues without visiting your school.
