CORS issue with sagecell.sagemath.org/service

[Jeremy Sylvestre]

Hi there, I've got some code that I haven't used for a couple of years that used to work with

sagecell.sagemath.org/service

but now is failing with

Access to XMLHttpRequest at 'https://sagecell.sagemath.org/service' from origin 'https://sites.ualberta.ca' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Is this service no longer supported?

Thanks,

this URL is not working, but

https://sagecell.sagemath.org/

is fine.
