Well Maybe you have a completely different situation.
Is it possible to build a more recent nginx version without the 
additional modules?

Please can you setup the tomcat as described in my answer.

Please can you try to run the connector with debug on.

http://tomcat.apache.org/tomcat-8.0-doc/logging.html#Using_java.util.logging_%28default%29

I would try to use this.

org.apache.catalina.session.level=ALL
org.apache.coyote.http11.Http11Protocol.level=ALL

Pay attention this will produce a lot entries in the logs and could have
some impact to the performance.

The standard setup have also some low limits maybe you must increase
this limits.

Maybe I have missed it but which tomcat version do you use?

Please also setup nginx with debug option as described here

http://nginx.org/en/docs/debugging_log.html

What's the error line(s) on the tomcat site?

Please can you also post the current 'conf/server.xml' with all
'Connector*', thanks.
