Thank you so much for the reply, I also should add that this is not through the EPIC or Rio but on a normal windows pc that is running node-red that is used to communicate with a EPIC.
I also tried adding https instead of http and now get the following error
curl: (35) schannel: next InitializeSecurityContext failed: SEC_E_INVALID_TOKEN (0x80090308) - The token supplied to the function is invalid
