The fact that only one session out of the bunch isn't coming up indicates that it's not an MD5 or ASN issue, though, as they are all defined within groups and not individual definitions within the neigbhor statements. Traceoptions simply show that the attempts timed out. LS1 is not responding at all to the incoming request from MX2, nor is it even *sending* a TCP SYN to MX2 in its own supposed session request (LS1 is not in passive mode).

Have you tried enabling BGP traceoptions to see if that logs more useful diagnostics?
