The remote server returned an error: (401) Unauthorized


I get this error when I try to sing with Twitter only on my production server. On the dev server and locally it works fine!
Of course I’m using the same code and settings!
What can it be?
I tried a lot of accounts, applications, consumer keys, consumer secrets but I’m still getting the error only on the production server!

I’m using .NET library DotNetOpenAuth.
Please help!


Seems it was wrong server time issue…
Thank you, Twitter “developers”
