Debug toolbar doesn't show if using a docker webserver container

[Eraldo]

I tried the solution approach to auto detect the correct IP and add it to the INTERNAL_IPS:

INTERNAL_IPS = ["127.0.0.1", "10.0.2.2"]
if env("USE_DOCKER") == "yes":
    import socket

    hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
    INTERNAL_IPS += [".".join(ip.split(".")[:-1] + ["1"]) for ip in ips]

This correctly detects my "django" container ip (172.18.0.5) and adds it to the INTERNAL_IPS.

However I am using a caddy webserver (172.18.0.6) and so the debug toolbar does not show in the end.
If I manually add 172.18.0.6 to the INTERNAL_IPS, it works as expected. (just to confirm)

Any ideas? 😅
