@bit4woo do you have any host to share to reproduce this scenario?

host -t cname docs.hackerone.com

docs.hackerone.com is an alias for hacker0x01.github.io.

nuclei -t technologies/tech-detect.yaml -u https://docs.hackerone.com -silent

@ehsandeep thanks for reply. I think you should try a PoC which type is "network".

I can reproduce this scenario with your domain "docs.hackerone.com"

you can try with this PoC : nuclei-templates/network/mongodb-detect.yaml

but something different this time : not only CNAME. ALL CNAME, A Record, IP Address show same error.

Hope it's helpful for you.

@bit4woo both errors are expected as none of the input running mongodb, let me know if have example where you have service running and nuclei unable to connect it.
