I cannot manage new Minecraft instances. Found this statement in an older discussion, that might resolve the problem:
So looks like the Spigot lot are returning a HTTP 403 (Access Denied) when AMP requests the version data as opposed to a browser. I've changed the user agent to get around this.
However I cannot find settings for User agent within AMP. How can this be resolved ?
Error is: "Unable to get Spigot version data from https://hub.spigotmc.org/versions/: Response status code does not indicate success: 403 (Forbidden)."
Minecraft instance can be created and started, however it cannot be managed. Also I cannot connect to that server instance.
