To return expected results, you can:

Reduce the number of search terms. Each term you use focuses the search further.

Check your spelling. A single misspelled or incorrectly typed term can change your result.

Try substituting synonyms for your original terms. For example, instead of searching for "java classes", try "java training"

docker login <cluster_CA_domain>:8500

fails with the following message after entering user and password:

Error response from daemon: Get https://<cluster_CA_domain>:8500/: unauthorized: authentication required

Before the upgrade, the docker login worked without problems.
All pods are also running correctly and there was no error during the upgrade.

Resolving The Problem

Different root causes could lead to this problem. Check below suggestions:

Ensure that the authentication for the Docker CLI is configured correctly:

Review your Helm chart versions. If some have not been upgraded to 3.1.1, you might also see problems with the Docker login. You will not see any errors for not upgraded Helm charts during the upgrade itself.
Either check the versions via the ICP UI > Workloads > Helm releases or via the command: helm list --tls If you see old releases re-run the upgrade again but delete the /.upgrade folder before:

For Linux® 64-bit, run this command: sudo docker run -e LICENSE=accept --net=host --rm -t -v "$(pwd)":/installer/cluster ibmcom/icp-inception-amd64:3.1.1-ee upgrade-chart For Linux® on Power® (ppc64le), run this command: sudo docker run -e LICENSE=accept --net=host --rm -t -v "$(pwd)":/installer/cluster ibmcom/icp-inception-ppc64le:3.1.1-ee upgrade-chart Afterwards, the Docker login should work again.
