error response in batch calls after web api upgrade: "site access denied"

Hi there. We have a curious issue after upgrading our PI WebApi to "ProductTitle": "PI Web API 2017 R2 SP1", "ProductVersion": "".


Batch calls that worked well before now return with a 403 error "Site access denied". We stripped the number of tasks in the batch down to a single item. If we run the identical call solo as a GET, i.e. using the exact same resource request, they work fine, both using a browser or code.


We're a bit at a loss over this one. Any ideas?
