Hello,
I did a quick search and didn't see this addressed yet but the warning is so large that maybe I wasn't getting the keywords. Has this warning in Chrome for an upcoming CORS changes been brought to the attention of Maker API devs?
[Deprecation] The website requested a subresource from a network that it could only access because of its users' privileged network position. These requests expose non-public devices and servers to the internet, increasing the risk of a cross-site request forgery (CSRF) attack, and/or information leakage. To mitigate these risks, Chrome deprecates requests to non-public subresources when initiated from non-secure contexts, and will start blocking them in Chrome 92 (July 2021). See Restrict "private network requests" for subresources to secure contexts. - Chrome Platform Status for more details.
I develop my own house panels and am seeing this now. I went to the Chrome flags, enabled this upcoming feature and, sure enough, no talking to Hubitat anymore so I am pretty sure most of my panels will break when this goes live.
