Hi everyone
this is what I tried and resolved this issue
edit your local.cfg file
and search for the parameter where dspace UI URL is defined
it should be something like this
dspace.ui.url = http://{your IP Address}:4000
below this line add the following directive
rest.cors.allowed-origins = ${dspace.ui.url}
Restart your tomcat service and try accessing the dspace over the network via the server IP address.
It should work just fine.
Thanks
