Problem with web enumeration with tools (Status: 503) gobuster

Hello, everytime I try web enumeration with tools, I get error on every directory (status: 503, length: 206). I need help, because usage and tools are ok. I was able to enumerate all machines in THM with no problems. But in HTB machines even edited /etc/hosts file to ‘IP > domain name’ and conneced to VPN dir enumeration with gobuster, ffuf etc. not working. Please Help

Have you tried any other HTB machine? This seems to be a common occurrence with Usage, so much so I’m not sure if it’s intentional (it’s just rate limiting, so --delay 1s in Gobuster)
