Start by tracing the request to https://sysupgrade.openwrt.org for profile dlink,dir-860l-b1 and target ramips/mt7621, focusing on the mismatch between version 24.10.0 in the request and the server's Unsupported version: 24.10.1 response. Reproduce the request and identify where version validation or firmware-image selection fails; done means the reported incompatibility is resolved or clearly surfaced to the client.
