Azure DevOps deployment getting 404 error

[BigTP25]

I am getting a 404 error when deploying to another ADF on a different subscription. If the ADF in my UAT environment doesn't exist, it will recreate it but runs into some problems because I have a SHIR and its linked to this UAT ADF environment...so blocker. If the UAT exists, it says "The remote server returned an error: (404) Not Found." Anyone have this problem? Kinda stuck...
