openlayers tile server tiles tiling scheme

One Answer

So basically i had to change the type of tile from ol.source.tile to ol.source.XYZ. I replaced this line of code

var templayer=new ol.layer.Tile({
title: "Czone",
 source: new ol.source.Tile({ url: 'https://conze.pt/app/climate- data/data/meantemp/6/maptiles/{z}/{x}/{-y}.png' })

});

with this

var templayer=new ol.layer.Tile({
title: "Czone",
 source: new ol.source.XYZ({ url: 'https://conze.pt/app/climate-data/data/meantemp/6/maptiles/{z}/{x}/{-y}.png' })

});
