Dear Andy, I appreciate your attention, thank you. For this issue, I have not done any testing with HTTPS so far, just `roots://` and `xrdfs ... query`. When I'd mentioned issue 1736, I should have said it more carefully. Issue 1736 mentioned a similar issue to this one in the discussion (error_syscall), but the overall problem indeed seemed different (and related to https rather than root). It was the only issue I could find that was remotely similar. > We still need the TLS tracing enabled and what the log says when a failure occurs. I'd turned all the knobs I could find--`xrootd.trace all` and `xrd.trace all`--on the server for the log output shared above. I'd be happy to make further changes and repeat.
