    Hello. I'm facing an issue on my website. I have some pages with a lot of small images (more than 500), and sometimes the browser don't load all requests, causing the load bar on the browser to not finish. This happens only on mobile browsers. When its happens, i can't access any of page on my website, only if i restart my mobile connection wifi/4g. I already added lazy loads on my page/images, but the problem still happening. When my connection is fast, this problem doesn't happens. I saw there some options on that can solve this issue but i did not know how to manage it, so i ask your service.

    I have created a WHM/cPanel VM server from the Azure Portal, but the server will not accept any incoming connections even though exceptions are added to the Network Security Group (NSG) within Azure. I have already created the VM with the WHM image by media3 from the Azure marketplace and can SSH into the server. I have tried adding rules and also disabled the firewalld and tried using IP tables, but I cannot open ports 80, 443, 2083 and 2087 and therefore cannot access WHM/cPanel from the internet. I have clarified that everything from the Azure side is correct, rules added to the NSG, so the problem is within CentOS.
