Andrzei Novak reported, that he was trying to access root://grid-cms-xrootd.physik.rwth-aachen.de:1094//store/user/anovak/PFNano/106X_v2_17/ggZH_HToCC_ZToQQ_M125_13TeV_powheg_pythia8/RunIIFall17PFNanoAODv2-PU2017_12Apr2018_94X_mc2017_realistic_v14-v2PFNanoV2/210101_180245/0000/nano_mc2017_1.root file through xcache
at https://coffea.casa.

Ideally it should work through using root://xcache//store/user/anovak/PFNano/106X_v2_17/ggZH_HToCC_ZToQQ_M125_13TeV_powheg_pythia8/RunIIFall17PFNanoAODv2-PU2017_12Apr2018_94X_mc2017_realistic_v14-v2PFNanoV2/210101_180245/0000/nano_mc2017_1.root but we are getting now Operation expired.

>>> uproot.open("root://xcache//store/user/anovak/PFNano/106X_v2_17/ggZH_HToCC_ZToQQ_M125_13TeV_powheg_pythia8/RunIIFall17PFNanoAODv2-PU2017_12Apr2018_94X_mc2017_realistic_v14-v2PFNanoV2/210101_180245/0000/nano_mc2017_1.root")
