When I open it on mobile, it takes too long to reload, but when I open it on desktop, it can open immediately, but when I check the page speed optimization on page speed insight, it takes a long time, then it says the below error. i

ops! Something went wrong.

I think that you should give the URL of your page here and I can help you to check the reason why you can not check it on Google Page Speed.

I hope that I can get your response soon
