Can a signer sign the same document 2 times?

[Tania252048940pqn]

I have a document with the same user assigned as signer 2 times, when I call the enpoint to get the 

signingUrls, and I access to the link it works fine the first time, but when I try to do it again for the second signature, I get a "Please login as an authorized signer in order to view and sign this document." message, if I use this link in a incognito window it works fine, so the link is correct, but I can't see the document assigned to me again even when is the same user. Also if I click the email link works fine, does anyone has an idea why is this failing?
