I logged on from Mexico and again with my UK VPN switched on .
Try 12 go asia.
It seems it has been blocked from outside India. I had to ask my relative in India to book ticket for me. Please tweet on Indian Railway account to get it opened for access. I am going to do the same.
Certainly not for all countries at least,I am easily able to log in (and even able to create a new profile) in last 3-4 days from overseas.

I can,t do that , there is no connection possible with IR , so how can i contact them ...?
Try using a free VPN like Cyberghost.
I just tried accessing IRCTC via Netherlands using Cyberghost but couldn't. But it was fine via the UK. Also no problem direct via my Mexican ISP. So it seems some countries are getting blocked. Maybe the US is also one of them.
May be problem is related to EU GDPR.
