Hi, @magro, please help if you can

I am trying to integrate the MSM into our application. I followed all the instructions and couldn't get it working. The logging are the following: 09-Nov-2017 13:19:36.488 INFO [localhost-startStop-1] de.javakaffee.web.msm.MemcachedSessionService.startInternal starts initialization...

looks like it is unable to create a sessionid with -n1 or -n2 in it. Not sure why,

This is application is hosted by Tomcat 8 and sticky session behind the load balancer.

This is my context.xml for n1 node <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:10.92.132.33:8443,n2:10.92.132.34:8443" failoverNodes="n1" sessionBackupAsync="false" requestUriIgnorePattern=".*.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" /> Context.xml for n2 node

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:10.92.132.33:8443,n2:10.92.132.34:8443" sessionBackupAsync="false" failoverNodes="n2" requestUriIgnorePattern=".*.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" />

We have two servers hosting this application. So I made one of them n1 and another n2.

Could you please see any issues with my configuration?

Thanks Tony
