DHCP lease expires every 8 hours on RTL8101/2/6E

Hello, my computer is having an issue with dhcpcd. When it connects to the network, it works fine for 8 hours or so, then dhcpcd says "DHCP lease expired" and connection stops working.

сен 20 05:29:53 polyzium-server dhcpcd[348]: enp1s0: DHCP lease expired
сен 20 05:29:53 polyzium-server dhcpcd[348]: enp1s0: soliciting a DHCP lease
сен 20 05:30:00 polyzium-server dhcpcd[348]: enp1s0: no IPv6 Routers available

To make it work again, i need to reconnect the cable.

I am using RTL8101/2/6E ethernet controller, How to fix this issue?
Thanks.

Re: DHCP lease expires every 8 hours on RTL8101/2/6E

You got the lease for an infinite amount of time ...... but it expired? Was there any dhcpcd log entries before that which may give a clue?
Can you enable dhcpcd debugging and get more output? Also, what dhcpcd version are you using?

Can you enable dhcpcd debugging and get more output?

Sry, i don't know how to enable it

Add the word debug on a line by itself in /etc/dhcpcd.conf

Re: DHCP lease expires every 8 hours on RTL8101/2/6E

OK.

So we can see that dhcpcd gained an infinte lease, applied it, detected carrier was lost, expired the lease, detected carrier up and then starts sending DISCOVER messages which are then not answered.

Let us try replicating it. Ensure that dhcpcd is running normally then issue these commands

ifconfig enp1s0 down
ifconfig enp1s0 up

Then also this test.
Ensure that dhcpcd is running normally then unplug the network cable and plug it back in.

Hopefully you can tell me the result of both of the above tests
