Additional context

This issue is occurring for all requests originating from Islamabad, Pakistan and otherwise working fine for other regions (tested from Azure CLI). Maybe there is geographic restriction?

Whenever I access any aka.ms links, it firstly gives connection reset error on browser. Upon page reload, it redirects me to correct webpage.
