If you can try use your mobile data as a hot spot to see if you can download the content.
There does seem to be a few issues going around since the latest update as other members are reporting similar issues.
Not sure if you resolved it, but for future searches for this error if helpful - I contacted nowtv online chat support here: https://help.nowtv.com/article/how-to-submit-a-complaint [they make it really difficult to find] and they advised that its something to do with a glitch on the number of devices you have on your account. There is no option to manually remove a device but the online chat person was able to do it for and now it works on all devices.
