ntmap with Netbox 3.0.8

[github6043]

Hi all, I just installed Netbox 3.0.8 and ntmap on the same Ubuntu 20.04 Host.
Netbox works fine, opening ntmap works also fine, I'm able to add groups and maps.
A soon as I open a map, I see Loading ... but get no map displayed. Any help would be appreciated.

The configuration.py looks like

PostgreSQL database configuration. See the Django documentation for a complete list of available parameters:

https://docs.djangoproject.com/en/stable/ref/settings/#databases

DATABASE = {
'NAME': 'netbox', # Database name
'USER': 'netbox', # PostgreSQL username
'PASSWORD': '!7p........M%', # PostgreSQL password
'HOST': 'localhost', # Database server
'PORT': '', # Database port (leave blank for default)
'CONN_MAX_AGE': 300, # Max database connection age

The ntmap, settings.ini looks like

db = dbname='ntmap' user='ntmap' host='localhost' password='ntmap'
max_objects_at_one_level = 100

[netbox]
db = dbname='netbox' user='netbox' host='localhost' password='!7p..........M%'

Try to access API manually in your browser: http://localhost/data/l1map?id=1
Do you see any errors?

The response should look similar to this:

{
    "result": "success",
    "results": {
        "interfaces": {
            "dc1-blfsw01": [
                {
                    "description": "",
                    "device": "dc1-blfsw01",
                    "mgmt_only": true,
                    "name": "c0",
                    "neighbor_class": "devices",
                    "neighbor_interface_mgmt_only": null,
                    "neighbor_interface_speed": -1.0,
                    "neighbor_interface_type": null,
                    "netbox_id": 1411,
                    "speed": 1.0,
                    "type": "1000base-t"
                },
...
