The difference is that your Exim does not do IPv6 (AAAA) record lookup.
Try to locate the reason... I'd propose to compare with pure Exim setup.
I just verified it on a IPv6 enabled 4.92.2 system, and it does show the
excat same error as Robert gets:
host in hosts_connection_nolog? no (option unset)
LOG: smtp_connection MAIN
