I logged into blue iris the other day and i noticed both of my cameras had stopped showing a video feed several days earlier. I get an error code 8000274c (timeout check ip address and port) on blue iris. I tried to type in the ip address of the cameras to manually log in but google says the site took to long to reach and just times out. I tried searching online to find out what to do but im not sure what to try next. I have my 2 dahua cameras plugged into a poe switch.
