Can’t Access Live View

I’m having problems accessing Live View on my wired stick up indoor cam. It has never been that good since new and is now impossible to access a live view. I have live view activated on in all 3 modes. Installed Ring Rapid and still no good. Reset router, turned camera off and back into setup mode up but still no good. My front door cam has no issues and connected to the same router. Frustrating !!!
