Pathlights won’t connect to bridge

HiHoping for some assistance. I’ve had my bridge and 7 battery pathlights working great for the last 3 years but recently all 7 haven’t been able to connect to the bridge (the lights have power, the wifi is good but there is no green connect light on the bridge and all the devices health checks say there is no connection to bridge)I haven’t made any changes to my network, they just seem to have stopped workingI’ve removed the bridge and lights and tried readding but I get the same problem. I’ve even bought a new bridge thinking that maybe the old one was broken but still get the same problems.A weird issue also is that when I add a light it says it needs to install an update but then just moves on and doesn’t tell me if update happened or not.Another weird issue is once the light is added, even though I can’t turn it on or off and it’s health says it’s unavailable , I still get motion alerts through ring so does that mean its somehow connected for alerts but not for control?Thanks
