I've tested with your config, but I see the button image just fine and I'm not getting kicked. From the error message you shared, it seems the client was trying to make a web request to resolve the image defined in the config, but somehow the request was made with an insecure connection, leading to the error and resulting kick. This isn't the fault of the plugin, as the plugin just declares what the UI should look like and provides the image URL. It's part of Rust's Community Entity UI (CUI) specification that plugins can declare UIs this way, and it's up to the game/engine to do the rest.

If this is still happening, you can try to swap out the image URL(s) for skin IDs which are fetched differently (via Steam instead of via Unity web requests).
