Hi Arif,

did the Umbraco backoffice administrator changed security settings for this particular user? Because it seams to be that you are not authorized to view the Content section of Umbraco.

Does this also happen when you go to other sections like Media or Developer which you normally have access to?

Hope this helps!

Hi Michael,

We have not changed any settings from backoffice. We just deployed a new change to our application which was working in all other non-prod environments and not in prod. The changes with same deployment still works on non-prod envs along with Umbraco.

Thanks,

Hi Michael,

We tried that too as per suggestions on some other posts on this portal. Still the situation is same.

There is no machine key defined in web.config.

Also the thing is, it sometimes logs us in and after some seconds of navigation on Umbraco portal it again logs us out and redirects us back to login page with the same error saying Session timed out. Log in below.

Thanks,
