Am I the only one who's Experience this

These recent days my Supremacy Website is slower to connect and too much time to load even though I turn the graphics into low but still

so I clear things out

- The website takes too much time to load yeah like 15 Mins

- I don't like to play on Mobile cause it's too laggy

- and After loading it takes time to load the Map? all black and slowly loading but not all of them is loading T-T

Please help me What is the Problem?

Is it in my Device? or on my Website?
