DNS name does not exist error

I have 3 Virtual machines being utilized. DC01-SPDEV (hosts the DNS manager within), SP2019-SPDEV (Dev environment where initial site collection was created) and SRV-SHAREPOINT (E) (Prod environment).

I first created a web application and site collection within SP2019-SPDEV via central administration. Next, I proceeded to add the web application and IP address within IIS Manager and also within the DNS manager on the DC01-SPDEV VM. Afterwards the site was accessible however after I backed up the farm via central admin on my dev server SP2019-SPDEV, did a powershell restoration on my prod server SRV-SHAREPOINT (E) I couldn't access the site on the prod server. I clicked the same configuration option instead of new if that is of any importance. Why does IE and Microsoft Edge, now give the error message Can’t reach this page The DNS name does not exist. Error Code: INET_E_RESOURCE_NOT_FOUND*. It seems that the DNS manager on DC01-SPDEV is affecting the dev server but not my prod server. Renaming the Connections folder to ConnectionsX did not fix the issue. Were there any steps that I should have taken that I missed?

Below are ULS errors in case they are pertaining to the issue in some manner.
