Server icon no longer works

Hello, I have moved my server from a normal gamehoster to a real server.

Earlier my servericon worked, unfortunately it no longer works with the same server.cfg.

As an error message comes the following:
[ citizen-server-impl] Could not open logo.png for reading.

My servericon is 96x96 and I have it in the same folder as server.cfg.
Also this is correctly named, as I said it worked before, now suddenly not.

The data are in /home/FiveM/server-data
