Hello @Ayesha_Munir ,
I see in the image that the Software Router try to connect to core.cytomine.com.
However, their is no Cytomine instance on http://core.cytomine.com/ and you will not be able to install an instance at this URL because you don’t have the cytomine.com domain name.
When you install Cytomine on a server, it is to be available remotely by you or others people through intranet/internet. To this end, you need to have URLs that redirect to the server where Cytomine is installed so you must have recorded the related DNS entries.
If you are not familiar with these operations, contact your system administrator for defining valid URLs that you will be able to set into the configuration.sh files.
Have a nice day.
