[SOLVED] Network problem to external switch

[Snapp R]

hey there,
i have some problem with the new version PVE 5.4,

after installing pve to server and giving an IP, i can't ping gateway, can't ping outside and inside..
it only happen when i connect it from server(port1, vmbr0) to switch(non managed, no vlan), although no ip conflict~

if i connect it directly to laptop/pc, i can ping and access the web management.. what did i do wrong there?

i'm not sure why, it doesn't work using 10gbps ethernet port.. but when i use the 1gbps ethernet, it works~

maybe because my switch is still 100mbps... .-.
