I was having difficulty getting my browsers to connect to HTB machines, even though I could wget, nmap, ping, et al with no problems. So I could wget 10.10.10.28/index.html but I coudn’t navigate to http://10.10.10.28 or http://10.10.10.28/index.html with any browser, even using a proxy like burpsuite. This fixed my problem! Thanks! Seems to be an issue with VMware and either kali2021 or rolling upgrade from kali 2020.4
