First time trying out Keycloak. I'm using the latest (26.2) version on RHEL 9.2 with JDK 24. As in the getting started guide I start it with start-dev and it tells me to go to http:0.0.0.0:8080, but when I use Firefox to go there, I get an empty page and it's always loading. Developer tools seems to indicate that there were no errors in the requests it did make. In the terminal I have a warning about "Non-secure context detected; cookies are not secured..." I've disabled tracking protection, etc in Firefox, and enabled cookies. I have a feeling it has something to do with Firefox wanting to use https, but obviously in dev mode it's http only. The guide doesn't instruct me to make any other changes/configurations so I'm confused why it's not working. |

This is an unforutnate default quarkus message - it does not mean you should use 0.0.0.0 as the host address. 0.0.0.0 is a special server bind address indicating "all interfaces". When you put 0.0.0.0 into the browser it will resolve to some interface - but possibly not localhost. This behavior is not clear / desirable and there was talk at one point of browsers not even allowing this, for example https://chromestatus.com/feature/5106143060033536 What you actually want to do with start-dev when https is not setup is specifically use localhost - http://localhost:8080 |

unfortunately I've already tried using localhost and 127.0.0.1 and they all behave the same way. For each one the tab changes to "Welcome to Keycloak" but the page stays blank. |
At the very least you should no longer being seeing the secure context cookie warning - if you are still seeing it, that would be odd. As for why the page would be blank with a proper localhost host, that seems like novel behavior. Can you provide additional information - such as using developer tools in the browser to see the exact responses from keycloak, debug logging, additional configuration you may be supplying via the env / keycloak.conf, etc. |

you're right. I don't get the secure context cookie warning now. Here's the output in developer tools. Let me know if you want to see the response of any particular request. |
|
Since you are getting valid 200 responses, maybe try another client to see what you are getting: Should show you an initial create user screen if an admin has not yet been created, afterwards it should be a 302 redirect to the admin console. |

seems I do get an html document back when using curl. I guess the problem is with my Firefox in Redhat. |
|
Very strange. |
|
I will try to install a different browser but this system is in airlocked environment so it's a bit tricky and may take me a while. Thanks for your help. |

yup...chrome just works... |
