Swiping doesn't work

[JoelOtter]

I believe this is because the X-Auth-Token header doesn't get set.

Please don't ask how I found this out

Apparently X-Auth-Token does get set right in the beginning when the code authenticates. Nonetheless the swipes do not work, an error {"status":"401","error":""} appears.
I checked the request headers in Firefox Developer Edition and saw this

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
Accept-Encoding: gzip, deflate, br
Accept-Language: es-ES,es;q=0.8,en-US;q=0.5,en;q=0.3

Any hint on why the coded headers are not sent ?
