Authentication lost when using more than one reverse proxies

using 2 redline server in front of 2 apache server in front of 1 tomcat server
user lost authentication
we have the following message in catalina.out
when we authentifie
Unable to render embedded object: File (remember-me cookie validation hash mismatch) not found.
Unable to render embedded object: File (remember-me cookie has been tampered with) not found.
Unable to render embedded object: File (remember-me cookie is being deleted) not found.

we of course remove cookies ( client side )

using 1 redline server in front of 1 apache server in front fo 1 tomcat server
every thing works fine
