Problem running the demo

[vvodicka]

Hello,
I am trying to run demo following the instructions in default mode, but I encountered following issues:

1. CORS - Access to XMLHttpRequest at 'https://dev.netztest.at/RMBTControlServer/testRequest' from origin 'http://127.0.0.1:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. - I tried to solve this by running chrome with disabled security using command open -n -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --args --user-data-dir="/tmp/chrome_dev_test" which seemingly helped, because POST to https://dev.netztest.at/RMBTControlServer/testRequest returned 200, but the response contained an error:

{
    "client_remote_ip": "91.233.248.21",
    "test_uuid": null,
    "result_url": "https://dev.netztest.at/RMBTControlServer/result",
    "result_qos_url": "https://dev.netztest.at/RMBTControlServer/resultQoS",
    "test_duration": "7",
    "test_server_name": "RTR https 100G AT #1 (Vienna)",
    "test_wait": null,
    "test_server_address": "vie1-httpv4.netztest.at",
    "test_numthreads": "3",
    "test_server_port": 443,
    "open_test_uuid": null,
    "test_server_type": "RMBThttp",
    "test_server_encryption": true,
    "test_token": null,
    "test_numpings": "10",
    "test_id": null,
    "loop_uuid": null,
    "provider": null,
    "error_flags": null,
    "error": [
        "Could not connect to database."
    ]
}

2. some unknown websocket error occured after a couple of logs:

Is there something I am missing? Or do I need to run the whole stack including measurement server, database server, backend etc. instead of trying to connect to the default demo server?
