Itr 1 filing issue error 404 page not found

i have also getting same issue last 3 days

its a technical glitch

Same issue also facing with us when filling IFOS Details.

Did you find any solution for this?

You can avoid this glitch if you file the the return with icognito mode (CTL+SHIFT+N) of browser with fresh filing.

Today its 404 error resolve by department 

I said there will be no glitches if u file with incognito mode. I just filed the returns. Have u tried with that mode ?

if still glitches in incognito mode then rest it to the god or it portal
