Cannot connect to domain controller while trying to authenticating network shares

Hi
We recently deployed ZTNA WARP in our environment and gradually we starting to notice that for some reason ends users unable to access resources such as on-prem network shares.
Our end user devices are registered to Azure AD however we have two type of file server, first in Azure side and second on on-prem DFS. I have been trying find out if someone out there having the same issue. I have tried to look for an answer and landed on Sophos article where someone having same issue after implementing Sophos ZTNA. Do we have similar configuration in Cloudflare?
