I think I may have found the issue. This was happening on V1 Cameras for me. Also, on the rare occasion I could connect it would take 3-4 seconds to refresh the frame on the video. From other posts (Frame rate dropped to 1/3fps) I found that even though the firmware stated it was up to date, it was not. All my V1 Cams state they are up to date with Firmware 3.9.4.16. The latest is 3.9.4.32. I had to follow the instructions here to update the firm ware -https://support.wyzecam.com/hc/en-us/articles/360031490871-How-to-flash-firmware-manually (It wasn’t working first - I had to delete all other files from the SD and rename the file as it mentions to FIRMWARE_660R_F.BIN) This has fixed the video issue at least but I have to monitor to see if it fixes the connection error 13.
