I am trying to start the grpc server with the property
quarkus.grpc.server.use-separate-server=true
in that case, i am getting the below error during server start up

But when I start the grpc server with property
quarkus.grpc.server.use-separate-server=false
the grpc server starts but the client is not able to access the server
I am getting the below error on the client side

How do we overcome this issue?
when starting up a quarkus service (v2.1.1), and trying to connect to a keycloak instance (v15.0.1) I am getting the following exception stack trace:

Here are the configs I have put:
# OIDC Configuration
quarkus.oidc.auth-server-url=https://<HOST>/auth/realms/<REALM_NAME>
quarkus.oidc.client-id=<CLIENT_ID>
# quarkus.oidc.application-type=service
quarkus.oidc.credentials.secret=<SECRET>
quarkus.oidc.tls.verification=required
# Enable Policy Enforcement
quarkus.keycloak.policy-enforcer.enable=true
Anyone got an idea what's wrong here?
Thanks to a comment above I found this quarkus config here to be helpful:
quarkus.log.min-level=DEBUG
quarkus.log.category."io.quarkus.oidc".level=DEBUG
Which gave me this error:
Caused by: org.keycloak.authorization.client.util.HttpResponseException: Unexpected response from server: 400 / Bad Request / Response from server: {"error":"invalid_client","error_description":"Bearer-only not allowed"}
So clearly, I had misconfigured the client inside keycloak. Too bad the original error message didn't give me that information by default.
After following all the steps for setting up a JMS client ( How to configure JMS in JBoss EAP 7?),
I have the following lines of errors:

I took those URLs and started to look for what happened. The server is reporting a 404 on those links. I remove parts of the path I find out that:
http://repo1.maven.org/maven2/org/grails/plugins/
This doesn't exist.
What gives? Is this a maven error or something to do with Grails? Are we experiencing an outage that will be fixed or is this something that I have to tell someone is broke?
I'm getting an error while connecting to a MSSQL server in iReport designer on Ubuntu.

Is there anything I've missed?
