DHCP times out in ethernet example

I try to run the example "Nios II Ethernet Simple Socket Server

on MAX 10 FPGA Development Kit". However, instead of

"Acquired IP address via DHCP client for interface: et1¨

in step 7 of the manual I get after some time

"DHCP timed out, going back to default IP address(es)"

How can I

1) make DHCP not time out, or

2) discover what the "default IP address" is?

Thanks in advance for answering.

    As a first step, use an Ethernet analysis tool to verify your packets are correct. Wireshark is good. I like to use it in a bridge configuration between the device and the network. See the Wireshark documentation for details on how to set up a bridge.

    Thanks for your help. I finally solved the problem as follows:

    - Disabling DHCP in the BSP

    - Giving the PC a fixed IP address

    I do not know why this works, although I can imagine that

    things get less complicated due to these measures. At least now

    it is fun to follow the simple communication with Wireshark.
