Hello!
We have a multiserver setup. When i try to access a user mailbox via view mail button i get the following error:
HTTP ERROR 400 invalid request: missing required param: preauth
URI: /service/preauth STATUS: 400 MESSAGE: invalid request: missing required param: preauth SERVLET: PreAuthServlet
The admin interface is being reached by removed link and the webmail interface by removed link
Both are behind a HAProxy.
Does anyone have an idea where to look at?
Thank you
Karl

I tracked it down a little bit further:
When accessing via internal LAN IP everything as working as expected but when acessing via external DNS name it breaks. Also everything is sitting behind an HA-Proxy. I am wondering because the same setup works with zimbra 8.8
