Excellent. Thank you! I was thinking I ought to be able to strace this
but had forgotten that one could attach strace to a running process.
Here's the output:

directory)

Since processes frequently iterate through a series of possible
locations for needed files, plus many that aren't needed but just
checked for, I assume most of these are spurious, and the last one is
probably the one that's causing the problem.
Indeed, there is no c33a80d4.1 cert file. I'm not familiar with the
details of the TLS mechanism. Is this a file that's expected to be
there as a result of the TLS negotiation with the remote server?
