Live view no longer available on security camera

As of yesterday I can no longer go to live view on my wired security camera. I can activate the lights and alarm but not see anything. I have checked the WiFi signal, which is strong. I have reset the camera and reconnected it, same issue. I've checked my data settings and they are unchanged. I have changed from home WiFi to Chime, no luck. My doorbell is still working fine, but I'm running out of options to get my camera to work again. Does anyone have any suggestions? Thanks!
