Dutch-MeshCore firmware before merge 32dd8ad (2026-10-19) does not accept a scheme in mqtt1.server: it builds <proto>://<host>:<port> with proto from the port alone, so mqtt://host became mqtt://mqtt://host:1883. Reported by an observer operator on the live instance. The mail now writes the bare host and adds a scheme only when the port would pick the wrong one (for example TLS on 8884), which needs firmware from 2026-10-19 or later.
