The personal account pages of the NS website do not seem to be very reliable given some previous user reports on this community. Therefore, I'd recommend you really do try again a bit later, hoping that the problem has been resolved.

Thanks for your response

, but the main problem is on NS application not a website.

I'm always getting an error message, and I will attach a screenshot to this reply.

Good afternoon Bassel80 and welcome to the NS Community!

If you have been able to succesfully log in to your Mijn NS account on the website and it is purely a problem you're experiencing in the NS App, I would recommend to use the option in the app to contact app support. You can find this via the button ‘more’ and then ‘App support’ at the bottom.

Usually, the NS app doesn't work for me when the website does. I'd recommend using the website in that case. The mobile site (fortunately) is rather good as well.

doesnt fix it as apparently you need an app to show your e ticket and showing it via online version is not good enough….. very old fashioned and app is just very bad

No, nowadays you can also show the eticket in pdf format. It doesn't have to be loaded in the app.
