Police raid on your home/company. Malware on a router. Malicious actor in the server room. Possibilities are endless.
SSL added and removed here ;-)

It doesn't even have to be on the router, just the same network segment plus some ARP spoofing tricks (assuming your switch doesn't have ARP spoofing protections or they haven't been enabled) could be enough to MitM a connection.
