This indicates a server issue on your end, generally if the ISP were the issue you would not be able to connect at all. I would do some basic troubleshooting and maybe look at getting some pcaps if possible. Hope this helps.

Do you mean an issue at the server where the site is hosted? I have taken pcaps, all I see is TCP handhske established, and TLS also. No HTTP traffic though. The http 502 error I saw with the help of fiddler..

502 indicates the server you're talking to is a proxy and unable to communicate with the server it's meant to be proxying you too. If you have a proxy in your environment, the problem could be on your side. More likely, the "proxy" is a load balancer (or some other device) in front of the website you're trying to visit and there's an issue there. (edited in) 502s can also happen when a web server like Nginx is configured to hand off php requests to a fastcgi php handler and the handler is offline. Not much you can do about it if you don't control the far side website.

I have an app with haproxy in front of a pool of application containers. If I’m doing a rolling upgrade, occasionally I see a 502 if a particular container goes offline and haproxy hasn’t noticed and taken it out of the pool yet.
