All,
I've seen some problems lately that are hard to debug and may cause you
to waste valuable time.
In short, if you face "strange" issues related to authentication,
specially when trying features that make use of WebSockets (ie: add
deployment), make sure you are accessing the web UI via 127.0.0.1 , and
not localhost .
In case you are interested in the details, keep reading.
Upon login, Keycloak issues a token for the client, taking the auth
server host into consideration (as the "issuer authority"). If you use
localhost, then that's the hostname that Keycloak will use inside the
token. This value is later used to validate the incoming token. Ideally,
all the hostnames would be a match, and that's usually the case if you
use the "-b" switch when starting Wildfly. But if you don't specify, we
fall back to 127.0.0.1 [1] , causing the "backend call" to be 127.0.0.1,
while the "frontend call" came via localhost.
I have a couple of ideas on how to solve this in our side, but until a
fix is done, tested and merged, please use 127.0.0.1 on the UI.

Team,
I prepared a workaround for this and performed a release of accounts
with the fix.
I sent also PRs for all projects that are consuming Accounts, as per the
"Component Dependencies" from our documentation[1].
Some components were using an old version of accounts, while others were
two versions behind.
- For agent/command-gateway, this change is required to fix the
127.0.0.1 vs. localhost issue (HAWKULAR-615).
- For most of the components, this change is optional and there's no
harm in updating. This is valid for components that were on 1.0.12.Final.
- For components that were on very old versions (1.0.1, for instance),
it might be wise to wait for the MS5 release before merging the PR. As
far as I *remember*, there were no breaking changes on the API, but we
have a release in a couple of days :-)
