Maybe you can provide a link to the source code or post some snippets of your configuration of Keycloak in your applications? It’s just a guessing game at this point as you don’t provide any details about your setup.

I pointed out a ‘maybe’ wrong configuration in your url as it include = instead of : in the url

Hey @zonaut,

I have the same Issue. I’m also getting a “Failed to Load URL” response.  
I already asked on stackoverflow, could you please have a look?  
[This](https://stackoverflow.com/questions/61142611/keycloak-failed-to-load-urls-in-spring-boot-application) is the link.

Thanks for the help.  
Best Regards,  
Johannes

Seems like the placeholders are not replaced? Normal syntax is ${keycloakserver} for Spring Boot, are you using another method of replacement?

Hey,  
thanks for the respond. I replaced it there because it was a running server.  
This is the local error Message:

Can you access [http://localhost:8081/auth/realms/public-library/.well-known/openid-configuration](http://localhost:8081/auth/realms/public-library/.well-known/openid-configuration) from the browser?

Yes,  
I can access this site. Thats the thing that suprises me.

I’m running keycloak in a docker container.

Is you keycloak docker container running in host mode or on a bridge network which is the default?

Yes this works too.

I can also login a user via postman. I’m getting a correct session and everything.

I think my backend cannot access the keycloak config, but I dont know exactly why.

Thanks for the code.

My Spring Boot app is running on localhost.  
It is already connected to another docker container, which holds the database of the app.

Solved it.  
I tested a few things, and I got an error which mentioned an “android.jar”. That was suspicious.  
I noticed that my configured sdk wasn’t the java sdk, it was the android sdk.

This lead to the error message.  
Now I’m just getting an 401 error message and can work from there.
