Hello could someone please help me with this issue?

received packet on enxa0cec8774ad4 with own address as source address (addr:fe:41:5c:5b:da:26, vlan:0)

Code: 
root@pve:~# cat /etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

This usually occurs when you have a loop somewhere in your network topology that causes packets from the PVE host to be sent back to the PVE host.

this cant be happen because i already youse STP on Switches

The message seems to indicate differently, since it means that you have received a packet that you have sent from your PVE host, so somewhere in your topology packets from your PVE host get sent back to it. Can you post the output of ip a ?

Are enx000ec6bdbf5c and enx000ec6bdbf5c on the same switch? How does the topology look like? Since the source address is fe:41:5c:5b:da:26 - as indicated by the error message, but I cannot find it in the ip a output: Do you know where that comes from? Did you make changes to the setup in the meanwhile?
