Google Chrome return error on self signed Certificate ERR_SSL_KEY_USAGE_INCOMPATIBLE

After update chome to the latest version all my website with self signed certificate not coming up, on other browsers they works .

The root cause of this issue is a Chrome Variation, which you can read more about in the Chrome release notes for versions 115, 116, and 117, available to read in Google’s previous release notes. There is no flag you can adjust to revert this variation, but Chrome has provided the policy RSAKeyUsageForLocalAnchorsEnabled to temporarily disable this variation while you update your certificates

To Fix this problem delete the file “Local State” from C:\users\(username)\AppData\Local\Google\Chrome\User Data” :

1. Close Chrome browser .
2. go to directory - "C:\users\%username%\AppData\Local\Google\Chrome\User Data"
3. Delete with Shift+Delete the file "Local State"
4. start Chrome and try again.

Cleaning browser cache and temporary files will help as well .

To close chrome altogether You can run from command prompt :

taskkill /im "chrome.exe" /F
or (for edge):
taskkill /im "msedge.exe" /F

For Microsoft edge the path is : “C:\Users\%username%\AppData\Local\Microsoft\Edge\User Data” . the same file is existing there. Though, keep in mind this will reset you edge status end some setting !!!

This is only temporary solution to enter “a must needed web site”. it will not work permanently

    This is a temporary solution. But after you closed chrome and open it again the problem is still there thats why i created simple bat file to force close chrome.exe and delete the local state file in one click of bat file. hope we can find a permanent fix for this.
