Getting error: " The following two devices, the WAN IP of the first device is conflicted with the LAN IP of the second device:" even subnets do not overlap. Tried to change them couple of times. Removing the first device from S2S just removes error message but the second device still does not connect. When starting S2S with AXT1800 added getting error -1001 briefly. The setting icon on S2S map does not work for this device. Factory reset did not help. Other thinks seems to be normal for this router except S2S
Could you please provide all the IP addresses of the devices? So WAN and LAN?
LANs are on the screenshot except ATX1800 which does not show it for some reason. It is 192.168.18.0/24
Main router and the last two are on home network 192.168.3.0/24
GL10 is on 192.168.100.0/24
GL8 is on 192.168.0.0/24

Also removing “conflicting” node GL20 from S2S does not fix the issue with GL18
Resolved by downgrading from v4.5.0 to 4.2.3
