7Talend HTTP Status 404 - ProxyServlet: /amc error

[Anonymous]

Hello, I'm new with this and I have a problem when I try enter to Activity Monitoring Console: 

I already checked if Tomcat is ok on my instance and I found this guy on Talend forum, he had a similar issue , he says that he can't ping the public IP for an EC2 instance, but can ping the DNS entry. I'm trying with this  and the message is "This site can’t be reached".
I have the file on my directory /opt/TalendTools-6.2.1/tac/apache-tomcat/webapps/amc.war*
Do you have any approach for resolver this? 
Thanks!

Hi,
Are you using talend subscription solution 6.2? Is there any error message in  Tomcat logs? Your network is Ok with you?
 Have you already reported a ticket on talend support portal? In this way, we can give you a remote assistance on this issue through support cycle with priority.
Best regards
Sabrina

Hello,
To open AMC directly in the browser outside TAC, use this URL: http://tomcat_URL/amc/rap?startup=amc
Thanks
