Ah, after spending some time on it and thinking about it, I was finally able to solve this problem for me. If you are not an NRI but if you're address is not fully updated in Income Tax eFilling account (https://www1.incometaxindiaefiling.gov.in/e-Filing/UserLogin/LoginHome.H T M L) then it wrongly assumes that you are an NRI and takes you to registration for NRIs. Giving India address in registration meant for NRIs make system to fail following error:
system has encountered some technical problem. please try after some time
Once I updated my complete address in the eFilling login and after 4 to 6 hours (there is database sync between these two systems) my "26AS" worked perfectly without me needing to login (or registration) into TRACES system.
I think the reverse may be true for NRIs as well. If they have India address in their income tax efilling login account but try to register with TRACES with non-India address then it might fail with same error. I'm just guessing this, I have not tried it myself.
