Orbi SXS80 Magenta light stays on even with connected internet

[Techdeskxy]

Recently I noticed that the status light magenta stays solid on my Orbi Satellite SXS80. I checked and there are devices connected to it that have access to the internet. In the logs it is showing that access was denied to WLAN. I do not have any MAC ACL setup.  All those MAC addresses are from different devices that are working fine. The main Orbi router has no lights on and working fine. I have rebooted all the Orbis and the Firewalla via the app. 

Setup: ATT modem connected to Firewalla Purple and then to the Orbi main router setup in AP mode. Firewalla is my router. I have the Satellite the main Orbi not being monitored by the firewall. 

Any ideas?

Not an Orbi Pro geek however, a brief peek on the fine documentation p.15 ff. does show

Magenta. The satellite failed to sync to the router. See The router and satellite do not sync chapter does start on page 225.

Yes, I had seen that before but it was not the case because the devices still had internet connection even though the Orbi was giving a magenta light. 

I was able to resolve, allowing ICMP ping to my home network. I guess the Orbi pings the network to check on the status of the connection. It was previously disabled for security reasons.
