Need help : unshared files

Hey guys,
OS : linux debian SID
Kubo version : v0.24.0 installed by ipfs-update (tryed with v0.24.0 rc2 and v0.23.0)
I’m using wifi behind a router. UPNP is up and port 4001 is forwarded on my computer.
firewall : port 4001 opened tcp/udp

When i’m trying to see my files here → https://ipfs.io/ipfs/my_CID or https://gateway.ipfs.io/ipfs/my_CID I have a 504 timeout.
my file is a simple txt (16 bits) in a folder.

All tests on ipfs check pass.

An idea ? thanks.
