I did what Joseph advised - deleted the camera and added it back to client. That seems to have solved my issue.
Both cameras load instantly now.
I realize that someone with 17 cameras is not going to like this solution. Good luck!

So far, cameras are connecting fine since I set static IP's on them.

Well, that only lasted a day. Same camera again is slow to connect. I have now set static IP addresses on the two cameras.
I'll see if that remedies the issue and post an update shortly.

I only have two cameras, both POE. One is a RLC 410 - it connects instantly every time I start the client.
The other is a RLC-520 - it takes awhile to connect - several retries and eventually it connects maybe 30 seconds or longer sometimes.
Ver. is 8.12.1 I upgraded firmware to the camera - no help.
Both cameras connect fine with the mobile app.
