Also, nothing is displayed on the browser side as well. only an empty page (screenshot attached). Can anyone please help me in this regard?

Thanks

When you open the web UI, it try to get the current registered UEs’ information from AMF, and if AMF is closed, the logger will report the error. A empty page is correct because it means that there is no registered UEs in the core network

Hi Jay16213
Thanks for your comment. Could you please tell me that how i will add the UE’s and in which particular file I have to make changes. Your cooperation in this regard will be highly appreciated.
