Here is an example of where there is an allow rule, but the process is still being blocked? Rule : https://imgur.com/z6l9LeB Log : https://imgur.com/jgPflDv Even when I delete the rule, run the app, wait for the prompt and re-create the rule the same behaviour happens? EDIT : I've reset the rules to default (to make sure there was not a conflicting block rule) and then tried again but with the same outcome. When I first launch this app I'm told Windows Defender has blocked this app and I can unblock it (which I do), this creates 2x Inbound rules (TCP & UDP). Other apps work fine. Not sure where else I should be looking to diagnose? Any help would be appreciated. Thanks!
