That error is being reported by the Minecraft software. You'll need to contact Mojang about that.

Otherwise I would double check that the file server-icon.png can be opened by an image viewer.

[botprzemek]

The icon is owned by opc user and has according permissions, I cannot load it from URL nor the file inside data directory.

[itzg]

To clarify, the error from the Minecraft server is reporting something invalid about the image file. Again, please discuss further with Mojang. That is not this image's software loading the server icon file at that point.

[itzg]

Is the commented out code what you were originally trying?

      # ICON: "https://imgur.com/a/zyf3nyO"
      # OVERRIDE_ICON: "true"

[botprzemek]

Yes indeed, this also was not loading.

You should fetch "https://i.imgur.com/pm9TjRd.png". Not https://imgur.com/a/zyf3nyO.
