Online error: Google browser encountered CORS error prompt: access to XMLHttpRequest at ‘ http://localhost:9990/ ‘ from origin ‘ http://xxx.xx ‘ has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space `local`.   An error occurred while upgrading the latest Google browser

Own error: open the electronic medical record access and PACS impact view in the patient holographic view, access the localhost: 9990 local program from a server program of the hospital, report a cross domain error, and prompt that the requesting client is not a security context, and the resource is located in a more private “local” address space, so local is not accessible

Reason: because Google browser has been upgraded, it is due to the increased access restrictions of Google browser. It should have been updated a few months ago. The solution is to use HTTPS

solve:

Step 1: open Google browser chrome://flags/#block -Secure private network requests
Step 2: find block secure private network requests. Set it to disabled
Step 3: close Google browser and reopen the web page to solve the problem.

Or access HTTPS instead of HTTP

Relauch may pop up after setting   Click     Reload Google browser

Go to the program again and click the electronic medical record access and PACS Image View in the patient holographic view to pop up
