Could not check origin for Phoenix.Socket transport

[nicedevil007]

Hey guys, I have a VM that is running AlmaLinux 9.4 with docker installed on it.
I can access my plausible page and try to register. After filling all needed fields to register nothing happens after I click on the register button.

In the docker logs I can find this:

plausible_db-plausible-1            | 13:36:20.166 [error] Could not check origin for Phoenix.Socket transport.
plausible_db-plausible-1            | 
plausible_db-plausible-1            | Origin of the request: https://192.168.125.2:8000
plausible_db-plausible-1            | 
plausible_db-plausible-1            | This happens when you are attempting a socket connection to
plausible_db-plausible-1            | a different host than the one configured in your config/
plausible_db-plausible-1            | files. For example, in development the host is configured
plausible_db-plausible-1            | to "localhost" but you may be trying to access it from
plausible_db-plausible-1            | "127.0.0.1". To fix this issue, you may either:
plausible_db-plausible-1            | 
plausible_db-plausible-1            |   1. update [url: [host: ...]] to your actual host in the
plausible_db-plausible-1            |      config file for your current environment (recommended)
plausible_db-plausible-1            | 
plausible_db-plausible-1            |   2. pass the :check_origin option when configuring your
plausible_db-plausible-1            |      endpoint or when configuring the transport in your
plausible_db-plausible-1            |      UserSocket module, explicitly outlining which origins
plausible_db-plausible-1            |      are allowed:
plausible_db-plausible-1            | 
plausible_db-plausible-1            |         check_origin: ["https://example.com",
plausible_db-plausible-1            |                        "//another.com:888", "//other.com"]

My docker compose looks like this:

services:
  plausible_db:

volumes:

and my .env file looks like this:

BASE_URL=https://<REDACTED>
SECRET_KEY_BASE=<REDACTED>
TOTP_VAULT_KEY=<REDACTED>

Plausible is running behind my nginx-proxymanager, which is configured this way:

Of course I added a ssl cert there as well :)

I have a friends environment running as well and he got it up and working with the same settings, just different URl and different Keys, same docker-compose.yaml etc. So what am I missing here?

Please ensure your BASE_URL is the same as the one you are using in the browser.
