I think the problems are unlikely to be related. Could you move your post (or create a new one) @proftech, with some more information about the specific problem you see and the error messages you can find?
The original problem is a bug in Brave (now fixed) and discussed in Kee extension 3.7.8 (brave/chrome) won't connect to KeePass 2.4.7
It’s normal for Kee to report problems connecting to KeePassRPC but the explanation for seeing these messages can be as simple as KeePass not running. Different browsers and operating systems can report subtly different messages and unfortunately some of these messages are impossible to handle in Kee - the browsers do not allow us to do so where WebSockets are concerned.
