Error while upload Icons

Hello everyone, I have a root server on which Pterodactyl is installed. I created a TeamSpeak Server with the program and always get the following error message when uploading icons:

“<18:48:06> Transfer “icon_26071999” reported: (could not open file transfer connection)”

I deactivated the Ubuntu firewall and already released the ports. Nothing worked, does anyone have a solution or an idea?

Thanks,

Manuel from Austria
