lgdc.uml.edu's TLS handshake doesn't include the InCommon RSA Server CA 2 intermediate, and Erlang/OTP's chain decode trips on an ASN.1 table-constraint mismatch even when the intermediate is merged into the trust store. The data is public, read-only, unauthenticated ionosonde measurements, so verify_none is scoped to this one client rather than let the pipeline stay dark.
