[jira] [Commented] (KNOX-2473) Problem with using KNOX to proxy
Tomcat
[ https://issues.apache.org/jira/browse/KNOX-2473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17237414#comment-17237414 ]
Sandeep More commented on KNOX-2473:
------------------------------------
Looking at the error message looks like the issue was connecting to tomcat
Service connectivity error.
is tomcat running locally on 8080? also, can you upload full gateway.log logs that will help us better identify the problem.
