Troubleshooting • Eth0 not working after upgrade PI 4

Dear all,

I have the following problem I have difficulties to solve.

I had a PI 4 working perfectly with an Eth0 connection configured as Static. After upgrade the Eth0 with the previously working IP and router adress is not functional : Physical signal is ok (Green / yellow led), but no connection with the network (no changes made beside).
Connection is working on Wlan,

Checked the dhcpcd.conf. > correct IP / Router static config.
Reboot Router > no changes
Reboot Router PI > no changes

Do you have any clue about what could have gone wrong ?

Thanks in advance for your help and advice.
