Just a quick shot: Run ip a to take a look of the actual situation of your network devices and IP addresses. Note the names of the devices, e. g. eno0, eth0 or enp4s0 etc. Make a backup of the "interfaces"-file by cp /etc/network/interfaces /etc/network/interfaces-possibly-bad. Use the editor of your choice to open /etc/network/interfaces. Compare the network interface names with those from "ip a". Do they fit? If not: correct them.

Hello mate.
Here are some screenshots of the results.
dmesg | grep eth - https://prnt.sc/IuQZC8xmvszl
ip a - https://prnt.sc/z5N8HgPOSXMg
cat /etc/network/interfaces - https://prnt.sc/fwNzvFKMg0KI
ping 1.1.1.1 - https://prnt.sc/_E7wfdT9pu8P
Please check them and advice me how to fix the networking problems on VPS because I cant activate networks on VPS and my current proxmox networks goes after each 15-20 minutes
