Check it in layers:
- is the reth interface on SRX-B definitely up when you have both links enabled
show chassis cluster interfaces
- is your LACP up between MX-B and the cluster - bearing in mind that you cannot have a single  LAG between MX-B and your SRX (it will need to be a LAG to each cluster node)
show lacp interfaces
- if the neighbor is only down on one of the RIs, assuming you have a VLAN between the MX and the SRX to carry each RI - double check that the VLAN is actually tagged on both LAGs between the two boxes
show bridge domain interface aex.0
