I've been using the Deco M4 3 unit mesh system for a few months now without any problems. I recently purchased a Tapo C200, which I added to the guest 2.4 GHz network without any problems.

I wanted to try viewing from a PC so tried to access the rtsp stream using VLC (following a guide on the forum) and got an error could not connect. After much messing around I decided to try connecting to the main network, and it worked immediately. I confirmed the issue by trying to connect to the guest network but got the same error.

I would appreciate if anyone has any suggestions to explain this issue, or even that I missed something about the guest network on the M4.
