Duo Addon; Login problems since Confluence Server v7xx ???

Hello Community,


since we have upgraded our Confluence (self hosted) server from 6.15.x to 7.0.3,

we sometimes have issues logging in onto Confluence;

I do not really know if Confluence tomcat server itself is crashing or - if only an Addon, like Duo Auth login-addon is responsible for the crash?


My current nasty workaround is:

-use the stop-shell-script:

sh /opt/atlassian/confluence/bin/

-wait and kill other like 'java' dead processes

-restart confluence via 

sh /opt/atlassian/confluence/bin/


What I have already done so far:

-increase java heap xms and xmx to 1536m each...

-internal RAM is ~ 9GB, which should be enough, it has always been enough on the machine for v6.xx

-update plugins

-disable unnecessary plugins...


1. Do you have any suggestings?

2. Which log would/could help me? For what strings should I search?

Java tomcat, and confluence tends to create lots of output, what to search for???


3. Shall I update to latest x7.xx-confluence?

Keep in mind that 'updating' is always a pain in the a... - it takes time,

to reinstall, and re setup plugins like Duo Auth 


4. And yes, I will consider writing Duo, but it is a big software company, usually the give a *** for small customers...

Funny thing to note, the Duo auth login is pretty old from 2017 - maybe it does not work very well with Confluence server v7 xx ??? v 1.4.3



PS: Ubuntu Server 16.04 LTS x64

using its internal OpenJDK  1.8.xx which comes within confluence..

duo login plugin v1.4.3 July 2017

Confluence Server 7.0.3

1 answer

Little update for those who are interested:

I have upgraded 7.0.3 to latest 7.1.1 

Funny thing: Duo snapshot from git seems to have been modified/updated i.e. on June 21 2019;


I will inform you guys if the updated version (including the updated Duo-addons) helped get the Confluence server more stable...
