Hi Andrew, Good morning. Thanks again for your help. All the client and server hosts have both IPv4 and IPv6 addresses. When querying the cmsxrootd-site1.fnal.gov redirector directly. I get: bash-4.2$ date; /usr/bin/xrdfs cmsxrootd-site1.fnal.gov:1094 locate -d /store/test/xrootd/T1_US_FNAL/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/AE237916-5D76-E711-A48C-FA163EEEBFED.root Mon Sep 18 18:09:30 CEST 2023 cmsxrootd-site1.fnal.gov:1093 Server Read bash-4.2$ date; /usr/bin/xrdfs cmsxrootd-site1.fnal.gov:1094 locate -d -m /store/test/xrootd/T1_US_FNAL/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/AE237916-5D76-E711-A48C-FA163EEEBFED.root Mon Sep 18 18:09:40 CEST 2023 cmsxrootd-site1.fnal.gov:1093 Server Read Both queries with/without "-m" option return hostname. ******** Also, for your info.
