It is always macOS, the famously defective OS.

Following up: After opening a support ticket with Synology, and receiving a similar (boilerplate?) response to the one they provided when I reported the first incidence of this issue, I found a different solution that solved the problem for me immediately, and without resorting to enabling AFP: After making sure I had backups of the current passwords for logging in as an admin on my NAS, I opened Keychain Access, searched all keychains for records related to my NAS, and deleted them. Once I did this, I removed/reattached my existing Time Machine backup shared folder in Time Machine, and it immediately worked just fine. It was able to continue backing up to the existing encrypted Time Machine backup, and has been working as expected, backing up every hour, since. Hope it helps!
