I'm running Unifi OS 3.2.7 and Unifi 8. I just switched from the USG. I found that in order to get node-unifi to work I had to modify the source code to change the URL to not have a port number. I tried ports 80, 443 and 8443 and all failed. I can't explain it -- is this a known problem

    //this._baseurl = new URL(`https://${options.host}:${options.port}`);
    this._baseurl = new URL(`https://${options.host}`);
