I have an updated node and it goes offline, what's happening Umbrel Os

This is worrying me. I have to constantly check the node, because sometimes hours go by without it connecting and I get an error. Does anyone have this problem and managed to solve it? It took almost a month to synchronize.

From what I see, this is a restart of Bitcoin Core. From this state, it takes a while to establish peers. Show us your logs to see what’s there. What’s the hardware you use and other applications you may be running? How stable is your internet?

Check the logs, any errors?
