You might not have permission to use this network resource

I recently got a new router, this is when the problem began. I am unable to use the windows file explorer to access files on my NAS; it is still discoverable in the Networks tab and I can access the web dashboard. I have deleted my credentials to log onto the NAS from user accounts in control panel but still I get the error that I might not have permission to use the network resource. I have tried accessing it on my phone and laptop and they both work like before but my computer keeps throwing this error

Does creating a new User (And granting permissions to this new User) allow for your system to access your NAS?
