CCRI web-interface authentication redirect loop

[asmith-nhsx]

Hello

I am trying to test out the reference implementation of the CareConnect API here:
https://data.developer.nhs.uk/ccri/exp. When trying to "sign in" to the open id connect server with my google id, I seem to end up in an infinite redirect loop. The log shows a CORS error just before redirect.

Apologies if this is the wrong place to report issues of this sort.

Thanks
Alex
