Was not sure were to post this. This is not a critical issue as it does not impact my running show and I have a work around for the connect part. When I start FPPConnect there are two issues. I am running xlights 2019.70 and FPP 3.5.5 or better on all 13 FPP instances.
1. I get two phantom entries for megatree. I call them phantom because they do not show an associated ip address. See attached screen shot. I assume I get two because all my FPP remotes attached to F16v2/3 get two ips listed. Both of the missing megatree ips do show up in the multisync page for the master.
2. two of my FPPs do not show up in the FPP list, but I can use the add FPP button, put in an ip for one of them and then both missing FPPs show up including both the FPP wlan0 ip and eth0 ip so 4 new lines are added to the list. One is the megatree listed in point 1 above. The other sits on my front porch and is the closest FPP to the master.
All FPPs are reliably accessed from multiple computers in the house or my phone. All FPPs work well in the show.
