Different browsers use different trust stores. Apparently the root cert is already installed into the system trust store:
2020/07/13 03:16:28.487 INFO pki.ca.local root certificate is already trusted by system {“path”: “storage:pki/authorities/local/root.crt”}
but not all browsers use it. You may also have to restart your browser. In any case, just add that root cert to your browser’s trust store (whichever one it uses) and it will work.
