Interesting, not sure I’ve ever seen that error before, and frustrating that it isn’t mentioned in the FAQ. 

Suggestions would be few, make sure that the WiFi is turned on the device you’re trying to bond the Sub to. It can’t be bonded to the Move, either. Try wiring both the Sub, and the speaker you’re attempting to bond it to, to your router with Ethernet cables, just to lock out potential wifi interference , since the Sub is trying to connect to its bonded speaker. It can do that through the router but prefers an WiFi connection to that speaker, not your WiFi.  And, of course, as previously suggested, contact Sonos Support directly to discuss it.

I fixed the trouble. Following the update the speakers switched to 5ghz network frequency, whereas the beam kept 2.4ghz. Beam can use only 2.4ghz frequency. So far I switched the speakers back to 2.4ghz frequency. Of course the mobile should use the same network to discover the system
