Accessing EOS data from outside of CERN network

Hi,
Does anybody know how to copy the EOS data while being on non-CERN network? E.g.

xrdcp -N  root://eosaliceo2.cern.ch//eos/aliceo2/ls2data/GC/ECS/2021-09-03_11-20/run0500463_2021-09-03T11_22_22Z/2021-09-03_00000003.tf ./

gives

Run: [ERROR] Server responded with an error: [3012] Unable to open file /eos/aliceo2/ls2data/GC/ECS/2021-09-03_11-20/run0500463_2021-09-03T11_22_22Z/2021-09-03_00000003.tf; Bad address (source)

while on CERN network it works (env. vars for XrdSecPROTOCOL and XrdSecSSSKT are set in a same way).

Cheers,
Ruben

Ignore the question, unix was missing in XrdSecPROTOCOL, sorry for spam
