Why is my ecommerce site responding slowly?

Hi, I have been using Shopify for quite some time and I realised from time to time I will get the issue whereby my website takes really long to respond and gives me an error. Do advise on what I can do.

Website: http://ecembroid.com/

What error do you see? A screenshot would be helpful if you have one.

I haven’t received my first 2 payouts because Chime says the payments failed because the account can only receive payments that is in the same name as the bank account holder. I’m guessing the payments come up as the business name. Not sure when I will receive the payouts now.

I then tried to change my payout information to my other bank account but it says old account must match what we have on file. I’m pretty sure I used the right account because Chime said they rejected the first 2 payouts. Please help if you have had this same issue.

I didn’t screenshot it previously but it is something like the above and takes really long to load the website.

Still facing the same issue as per the screenshow below.

I’m using Namecheap for domain name tied to my Shopify eCommerce account and getting this issue. Anyone has any ways to check why this happens?
