Symptoms
Client applications are unable to produce or consume messages. The logs for producer and consumer applications contain the following error message:
org.apache.kafka.common.config.ConfigException: No resolvable bootstrap urls given in bootstrap.servers
The Event Streams UI reports the following error:
CWOAU0062E: The OAuth service provider could not redirect the request because the redirect URI was not valid. Contact your system administrator to resolve the problem.
Causes
An invalid host name or IP address was specified in the External access settings when configuring the installation.
Resolving the problem
Modify your Event Streams installation and provide the correct external host name or IP address.
If using the UI, you can set the value in the External hostname/IP address field of the External access settings section.
If using the CLI, use the proxy.externalEndpoint parameter, for example:
helm upgrade --reuse-values --set proxy.externalEndpoint=my-loadbalancer1.com es1 ibm-eventstreams-prod-1.4.0.tgz --tls
