Uptime going down

I wonder, why my uptime is going down (from nearly 99% down to 68%). I have two feeds always on, one of them shows 98.6% uptime. My MLAT Region 12 Details show 99.2% health. MyIP shows all green. I have the stats package connected. I’m using adsb.im ADSB Feeder Images, feeding also FlightRadar24, Flightaware and adsb.fi, which all go with no problems, on RaspberryPi 4B with 2GB memory, 64GB SD-card. I’ve tried reboot, restarted containers, recreated containers, Feeder Dissociation and Association. What next? Or do I only have to wait? TIA Yrjö

Hello again,
I had changed Feed UID with new hardware with the same Receiver Name 12 days ago. Now I see two receivers on Leadrboard with same Receiver Name, but I cannot get hold of the newer receiver on Leaderboard. I have unlinked the older receiver but it still is visible on Leaderboard. How can I remove the old receiver? Does the old receiver drop off the leaderboard after 30 days?
