Device goes offline periodically and then instantly gets back online

My device goes offline almost periodically at every 5 minutes only to instantly come back up. On opening the terminal on Host OS and running journalctl command these are a couple of series of logs I found unusual.

Jun 22 07:16:07 0982ed2 kernel: Under-voltage detected! (0x00050005)

It would be nice if someone could help me out with this problem.

Hello @nishchayp .

kernel: Under-voltage detected!

Have you tried using a different power supply ? Under-voltage can cause hard to debug issues.

Hi @zvin, thanks for the reply.
Did change the power supply but the problem still persists. Please let me know if any other logs or command outputs might be helpful to figure this out.

Hey @nishchayp when you say the problem persists, do you mean only the vpn disconnections, or the undervoltage warnings too?
