Impossible to connect on the nextcloud with Keycloak

[zak39]

Hi everyone 🙂

I would like to use Keycloak to do tests and I cannot log in with Keycloak.

I followed the instructions : https://github.com/juliushaertl/nextcloud-docker-dev#keycloak .

I run a few docker containers with this command :

docker compose up proxy nextcloud ldap keycloak

Then, I tried to log in with keycloak :

But, when I clicked on the "Login with Keycloak" button. I get this error message :

So, I tried to connect on the http://keycloak.dev.local . But, I get this another error message :

I saw my configuration from Settings > OpenID Connect and the configuration seems good to me ?

I don't know if it's a bug or not. Can you help me, please ? 🙏

Looks like a typo in the URL:

keycloak not keacloack

Looks like a typo in the URL:

keycloak not keacloack

Thanks @juliushaertl , I am stupid ><

I retried with keycloak.dev.local and I have this error page :

And I always have the same problem when I would like to log in with keycloak :

I wonder if it's a problem with the port number (?) 🤔

The port numbers should not be needed as the request should go through the proxy container. I also cannot reproduce that, for me this works fine :/

[juliushaertl]

Maybe try restarting proxy with docker-compose up -d --force-recreate proxy

[zak39]

Arf... Always the same problem even after run the docker compose up -d --force-recreate proxy command...

[zak39]

I tried to delete all my images and recreate with docker compose up proxy nextcloud ldap keycloak and always the same problem... It's very strange... 🤔

[zak39]

I don't know if it's that, but the url is keycloak.local.dev and not keycloak.dev.local : https://github.com/juliushaertl/nextcloud-docker-dev/blob/172b158844e028858df4a1a4b258c1ec6330bf46/docker/bin/bootstrap.sh#LL132C1-L132C130

Ah I see, i think the auto setup doesn't take the DOMAIN_SUFFIX into account properly. However independent of that keycloak should be reachable in the browser through keycloak${DOMAIN_SUFIX}

[zak39]

Hmm... But, should I have access to keycloak.local in this case, no ?

In my .env file, the domain sufix is .local.

# .env
DOMAIN_SUFFIX=.local

If you write keycloak.dev.local in the project and in configuration files keycloak${DOMAIN_SUFIX}, I don't know if it can work with keycloak.dev.local 🤔

I tried with keycloak.local or keycloak.dev.local and I have the same result 🤔

[juliushaertl]

Can you check the container logs of proxy and keycloak if there are any errors or messages when you try to open keycloak.local in your browser?
