Error 400 unknown target uri but works after a while

Hello,

We are facing a very disturbing issue with our deployment.

We have two proxies nodes wich we are load balancing on using fortinet. The load balancing seems to work fine.

When we log in using windows basic authentication, we are having a 400 error 'unknown target URI', this happens going through the proxy for load balancing or the ip of the node itself.

Going in the logs, I can see that in the system proxy we have lines like the following one :

"Requested resources for targetId - ID - was not available, considered as bad request"

the most disturbing is that it works after a few minutes (litteraly), we can then log in and are able to navigate just fine in the qlik environment.

Anyone faced a simillar issue before ?

Thanks in advance .
