Anomaly report

I know this might be a dumb question, but was does this mean and how can I fix it? When I go under My ADS-B page I see this message under my map.

Anomaly report for piaware feeder with a mac address of xx.xx.xx.xx.xx.xx
ADS-B positions were last received from this feeder a while ago.

Thanks for the help…

I get that when one of my feeders is down for over a day or so. There may be a server issue at the moment too.

It’s been tracking threw out the day. My numbers were going up. But there not now.
