Definitivamente funciona quando você aumenta o zoom para uma área de mineração de carvão além de 1: 70K.
Se você verificar as capacidades, poderá ver que MaxScaleDenominator
está definido. Eu suspeito que o servidor esteja calculando que, na projeção interna dos dados, que é EPSG: 27700 (novamente, acho que provavelmente é), portanto, se você estiver visualizando no EPSG: 4326 (como você é), parece que precisa aumente o zoom para 1: 20K para ver a camada.
