Thanks for getting in contact and sorry to hear you are experiencing this issue, our team is currently investigating this issue but we have been advised that disabling IPv6 (if that is enabled with your router), has temporarily resolved this issue. You can perform this workaround using the steps below :
1. Right-click the network icon in the bottom right corner of your desktop, and click "Open Network and Internet Settings"
2. In the middle of the window that appears, click "Change Adapter Options"
3. Next, right click on the network adapter you are looking to change and then select Properties.
4. Now, uncheck the box for Internet Protocol Version (TCP/IPv6) and then click OK.
If you need further assistance with disabling IPv6, you may wish to contact your internet service provider, but you can always contact us directly via our social media accounts on Twitter / Facebook or our Live Chat service when this is available.
