Connecting to Target from home network

Hi

So I am currently doing the Blind SSRF portion of Server Side Attacks and I cannot connect to the target from my home machine.

I can only connect when I use the HTB VM is this by design or is there a way around this.

the target also has some brackets after the ip I don’t know if they are significant or not:

10.129.194.216 (ACADEMY-SSA-BLIND)

P.S first time encountering this kind of lockout with my home setup.
