Lately this happening to all, not just you. The heavy usage of internet is causing this issue on network side.
1. This happened with jio network. But when people switch internet or use from mobile data with different connection it works fine.
If the site is working fine from other device, then there is no issue with the website or forum.
DO not compare chatzozo or any other sites with social network like google, facebook and more. They got super catchy DNS, works like hell even with slow dead internet connection.
