Ory Community

right, that did the trick:
```  kratos-selfservice-ui-node:
    environment:
      - HYDRA_ADMIN_URL=<http://hydra:4445>
      - ORY_SDK_URL=<http://kratos:4433>```
that second env makes things work it seems (both 4433 and 4434 appears to work)… *phew*

You're kind of cluttering the channel with the repeated messages. It's better to just write a quick summary of your question, and add more details as a thread. Or just try to write everything in one go.

Yeah sorry, should have written it in a thread, if you watch the timestamps it was a few hours of debugging to figure stuff out (so initially i didnt know where it would end up)

noticed now that it wasnt actually `ORY_SDK_URL` i needed, it was `KRATOS_ADMIN_URL=<http://kratos:4434>` (it just defaulted to the kontekts of the SDK variable if not set)
