SWAN in up2university

Dear admins,
sorry if this post is a bit out of topic, but I have several students working nicely in SWAN through the up2university account, but since Friday last week the system gives error[1] when trying to open a jupyter notebook from CERNbox[2]

Even if it is not a central CERN service, since I do not see direct support from up2, could you please have a look or redirect me to the corresponding right person?
Thank you very much in advance,

SWAN could not start a session for your user, please try again. If the problem persists, please check:

  • Do you have a CERNBox account? If not, click [here].
  • Check with the service manager that SWAN is running properly.

Just to complete my previous post: trying to open swan directly from up2university in:

Thank you again

Hi @jfernan,
I’ve contacted the Up2U partner PSNC, which is the responsible for the deployment. I’m not sure what the level of support is there, since the project has finished, though.

Thanks Diogo!
Could you please keep me in the loop?
Thank you

Hi Javier,
the problem should be fixed now.

Best regards,

Thank you very much Michal!!
