Probably a routing issue. Shot in the dark would be that one of these routers is NATing traffic, and the other router doesn’t have a route to that NAT’d range.

Other shot in the dark, misconfigured bridging or similar where ARP isn’t getting forwarded and rewritten quite right
Or look for something mangling SRV records, Minecraft seems to use those more regularly than everything else.
