Here are some steps to solve this problem

Rohan offered a workaround and that works.

Install Google Chrome Extension - Browsec. This allows to access different websites as-if you are in a different country. Both Matej and Lubos confirmed that they are able to open LMI site.

Hi

Last month or so I was able to connect to LMI site only in 2 ways.
1. By my Android cell phone and that only if I used paid mobile data from my mobile provider O2. It did not work when connected by wifi.
2. By my (very old) computer in work - with operating system Windows XP.

So the only way to "participate" in contests is that in Friday I download the file in my work together with password and then later at home at the weekend I solve the tasks. No chance to submit anything in reasonable time.

Have you had a look at which internet providers you are using? It seems very likely that those with trouble use the same internet provider, which blocks / has trouble with logicmastersindia.com for whatever reason.

Rajesh's link above is useful. It would be valuable to know if those with trouble can resolve logicmastersindia.com, if they can ping its IP address, and where traceroute gets stuck.

I was able to connect to the site using browsec.
Thanks.

I was able to connect to the site using browsec, too.
Thanks.
