MJPEG feed loading delay

I am currently using VLC to encode my RTSP camera feeds from Unfi Protect so that they are usable on AT.

The issue I am having is that if I refresh one of my dashboards, the feeds will take 20-40 seconds to load. When using these Cameras to check all is ok around my property it can obviously become quite frustrating with such a wait before getting a live view.

Is anyone else experiencing delays with this?

I am using a server with plenty on resource for VLC.

I am having the delay with all devices whether it be edge, chrome, android tablets running AT app. Even tried safari on an iPad.
