Re: could not accept SSL connection: Success

Thanks, Michael, that's it, indeed! I had missed that part of the
OpenSSL docs. These PG instances are running on Ubuntu Focal hosts that come
with OpenSSL 1.1.1.

We had never seen these in the previous Xenial images because those
were using OpenSSL 1.0.2, and from what I've seen the bug was introduced
in 1.1.0.

Thanks again,
Carla
