Web interface not working anymore

I set up this server 2 days ago and have been running it constantly for the past 2 days.
Today after downloading slightly different code to my end node and restarting the gateway, the gateway lorawan files couldn’t been seen anymore in the web interface of the application server.
however when I look at the logs, the gateway bridge definitely receives the information, the network server is working and the application server as well.
Do you have any idea of why?
Thank you very much
