Could you please explain your setup little bit like :
- What is the Operating System of your VM ?
- whether your VM is domain joined or standalone VM?
- Where you have configured this forwarder ?
- is that port no 53 is allowed between your VM and DNS server ?
- What kind of DNS server you are using MS DNS or some DNS appliance ?
Also I could see another blog post where same type of issue was discussed. So mentioning the link below. You can check those answers as well.
Thanks & Regards,
