When I go docker pull hello-world I get the below error message:
Error response from daemon: error parsing HTTP 408 response body: invalid character '<' looking for beginning of value: "<html><body><h1>408 Request Time-out</h1>\nYour browser didn't send a complete request in time.\n</body></html>\n\n"

I have ensured that network exists and I can reach other sites. Please help
Update 1: The issue cannot be of setting MTU because I could pull the images from Docker hub a few days back on the same machine.
The issue cannot be of HTTP_PROXY either because I am in my home network
That error message looks like it's coming from a proxy server. From the docker pull documentation
The link to the instructions for configuring systemd with a proxy is straightforward.
The error message is little misleading. The problem was not that there was invalid character, but the network was misconfigured. I had one LAN interface and one WLAN interface.
LAN interface connects to a router A which forward requests to router B which was connected to internet. While the WLAN interface was directly connected to router B. I forgot to remove the WLAN configuration.
Once I ensured the WLAN interface is removed, things worked smoothly.
In short: Ensured DNS resolution works and that MTU is set right
