Snap Ubuntu error every day server new start

Hello Everyone,
i have a Ubuntu Server and i installed NC on it. It works fine but everyday the ubuntu server autorefresh itself and next day i have to make a new start to access the nextcloud website.

Can anyone tell should how to disable this???

Hi @aaaa

There seems to be some network connection or DNS problem on the server or in your network. Snapd cannot resolve the address

Does the server have internet connection? Does sudo apt update or a ping work?

Yes it is working but i dnt know why every day i have to restart it. After new start i can access my nextcloud website page. But every day making new start is not a soultion
