Ubuntu 20.04 Focal Fossa apt get update error

I am using Ubuntu 20.04 Focal Fossa, and from last couple of month I am noticing the apt update is not fetching any results. It used to work before that.

kaziray@kaziray-Lenovo-ideapad-330-15IKB:/etc/apt$ sudo apt update

This is my /etc/resolv.conf content:

nameserver 127.0.0.53
nameserver 8.8.8.8
options edns0 trust-ad

I have added the nameserver 8.8.8.8 recently, when I had found out that my sudo ping was not working, however ping was working.

I have tried with main server, India, Singapore mirrors, but all of them is giving the same error. I checked if my ISP has any firewall, I don't think so.

Ping works to archive.ubuntu.com or its mirrors as expected:

kaziray@kaziray-Lenovo-ideapad-330-15IKB:/etc/apt$ sudo ping in.archive.ubuntu.com

Don't know what's the problem.

Hello All, can I get some help here? Essentially it looks like, the apt doesn't find that I have an internet connection, why is that so?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
