Are there more errors for the same process?
Which LogLevel do you use?
mailgun is a #%$&@& wrt TLS: they configure weird requirements
and simply hang up if they don't "like" something.

You might want to update your sendmail version so you don't just
get errno= but also the textual representation.
On Linux 104 is:
/usr/include/asm-generic/errno.h:#define ECONNRESET 104 /* Connection reset by peer */

Was it ever?
