Set the DNS on your laptop to google dns 8.8.8.8 and 8.8.4.4 and see if it works
Tried that as well. It does not work.
By the way, when I use my Idea Cellular connection as WiFi on the same laptop, I get connected to all the sites. No DNS errors. The issue affects only JioFi connection. So much so that even the banking sites like onlinesbi do not work. Logically, I cannot use it on my VPN service for the simplest of the reasons.
I just want to know whether it is an issue with my laptop or something that has to do with Jio?
