This looks more like a problem with the source site, LRZ-LMU_DATADISK. The error message refers to the source URL at httpg://lcg-lrz-srm.grid.lrz.de:8443/srm/managerv2. Also, if I try to download from the source path, it gets stuck:

gfal-copy srm://lcg-lrz-srm.grid.lrz.de:8443/srm/managerv2?SFN=/pnfs/lrz-muenchen.de/data/atlas/dq2/atlasdatadisk/rucio/mc16_13TeV/35/cb/HITS.17137527._002530.pool.root.1 .

Can you assign a new ticket for LRZ-LMU?

I hope it's OK for me to mark this ticket "solved". Please reopen if I was mistaken.

Thanks, Tim.
