<div>I should mention that this happens whether or not I have&nbsp;<a href="https://[apimanLoadBalancer]/apimanui">https://[apimanLoadBalancer]</a>&nbsp;in the Root URL field for the Apimanui client, or whether or not I have&nbsp;<a href="https://[apimanLoadBalancer]/apimanui">https://[apimanLoadBalancer]/apimanui</a>/*
 in the Valid Redirect URIs, or both. However, if they are present I no longer see the DEBUG line &quot;replacing relative valid redirect with&#8230;&quot;; I only see the WARN message with the failure.</div>
<div><br>
</div>
<div>Also, it appears that the URL encoding is a non-issue; at least, I see the URLs encoded properly in the browser URL bar even if the &quot;inspect&quot; formats them with slashes and colons.</div>

<div>I am using Keycloak with the apiman API manager. Both are on AWS and are behind Elastic Load Balancers (Keycloak is clustered using JDBC_PING). When I request the apiman admin UI page (<a href="https://[apimanLoadBalancer]/apimanui">https://[apimanLoadBalancer]/apimanui</a>),
 I get redirected to the following URL:</div>
<div><br>
</div>
<div>&nbsp; &nbsp; <a href="https://[KeycloakLoadBalancer]/auth/realms/apiman/protocol/openid-connect/auth?response_type=code&amp;client_id=apimanui&amp;redirect_uri=">
https://[KeycloakLoadBalancer]/auth/realms/apiman/protocol/openid-connect/auth?response_type=code&amp;client_id=apimanui&amp;redirect_uri=</a><a href="https://[apimanLoadBalancer]/apimanui/index.html&amp;state=3/c48eec70-0fe9-44bf-9802-a351353f7600&amp;login=true">https://[apimanLoadBalancer]/apimanui/index.html&amp;state=3/c48eec70-0fe9-44bf-9802-a351353f7600&amp;login=true</a></div>
<div><br>
</div>
<div>Keycloak then displays the error &quot;We're Sorry&#8230; Invalid parameter: redirect_uri&quot;</div>
<div><br>
</div>
<div>In the Keycloak log I see:</div>
<div><br>
</div>
<div>
<div>&nbsp; &nbsp; DEBUG [org.keycloak.protocol.oidc.utils.RedirectUtils] (default task-7) replacing relative valid redirect with:
<a href="https://[KeycloakLoadBalancer]/apimanui/*">https://[KeycloakLoadBalancer]/apimanui/*</a></div>
<div>&nbsp; &nbsp; WARN &nbsp;[org.keycloak.events] (default task-7) type=LOGIN_ERROR, realmId=apiman, clientId=apimanui, userId=null, ipAddress=[IP], error=invalid_redirect_uri, response_type=code, redirect_uri=<a href="https://[apimanLoadBalancer]/apimanui/index.html">https://[apimanLoadBalancer]/apimanui/index.html</a>,
 response_mode=query</div>
</div>
<div><br>
</div>
<div>This looks to me as though Keycloak thinks that the redirect URI is a relative path. I also notice that the query string parameters for redirect_uri are not URL encoded by apiman. Would this be the source of the problem?</div>
