Big red Not Found

Dear Forum.

I’m trying to add a new site to my master 1.5.0p16 server.
When trying to login to to new site after haveing added all the information i get this page:

We are useing a ssh tunnel between slaves and the master and we connect like this

Where we have a custom port for livestatusm, gui and other.

The site is running. Can confirm this from omd status and i can load the webpage.
Distributed monitoring is enabled
What could be the issue here?

Did you check that name resolution working? The error message point to a problem of WATO http connection not the given livestatus in your post.
