Reporter @vasmarfas saw X2D archive cards land almost empty - only print time, no filament weight / layers / MakerWorld link / thumbnail - and Spoolman filament-usage tracking went silent on the same printer. Support bundle traces the end-to-end: at print start backend/app/main.py::on_print_start tries the usual FTP-download dance for the 3MF, every implicit-FTPS connect attempt to the X2D fails with `[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1032)`, ~2 minutes later "Could not find 3MF file for print" -> "Created fallback archive". Fallback path writes file_path="", file_size=0, content_hash=NULL, no layers / filament / model-link fields. Spoolman tracking degrades from the same root cause - both depend on the 3MF metadata parser. Proximate cause: Python 3.13's default ssl.create_default_context() negotiates TLS 1.3, the X2D's implicit-FTPS server on port 990 rejects the ClientHello. Same family as the P2S 01.02.00.00 bug from #1401 (post-Python-3.13 TLS-1.3 breakage), different wire-level failure mode (P2S completes the handshake and truncates with 426; X2D fails the handshake outright). Same fix shape: add X2D to backend/app/services/ftp_profiles.py with cap_tls_v1_2=True, plus N6 -> X2D SSDP alias. Every other model stays on negotiated TLS 1.3. Honest caveat: hypothesis-driven trial, not a confirmed root-cause fix. WRONG_VERSION_NUMBER could equally describe the X2D switching to explicit FTPS (AUTH TLS on plaintext greeting) or moving FTPS to a different port - either would need a different code path. Reporter has been asked to test this build; if the cap doesn't clear it the registry slot stays useful and the next diagnostic round goes to openssl s_client from a network-adjacent host.
