Unable to intercept with burpsuite on LAB burpsuite

My burp-suite is not intercepting the traffic generated by the lab "Burp suite " http://10.100.13.5/ police department website, but the burp can intercept the rest of the traffic except this
Please does anyone know why this is happening? I went to this website for more help Launching Burp Suite - PortSwigger, but seems like my settings satisfied all requirements
Please help
