Streaming error (wired stickup cams)

Hi - I have 3 wired (powered Ethernet) stickup cameras but always receive a streaming error when trying to access Live View footage from my phone. I have the storage plan and can view recorded footage so no issues with the cameras working. As I am using hardwired cameras and mobile data for the phone app the following is irrelevant but provided anyway - home wireless upload speed is generally \>35mbps and upload \>6mbps. I also ran a LAN speed test with download of 54mbps and 18mbps at the cable of one of the cameras. The ping was 6ms. My cameras run to a port switch with Ring Elit Power Kit running between cameras and ports, with all power lightS on and ethernet cables running the right direction. The power kit is closest to the switch. From a setup perspective I cannot see any issues, from a technical perspective I am seeking assistance. Thankyou
