The most common reasons are as follows：
1) The IPs of BGP peer cannot ping each other. At this time, you can use extended ping to check the TCP connection.
For example:
ping -a source-ip-address destination-ip-address。
2) The wrong configuration of peer IP or peer AS;
3) OPEN packet negotiation fails，OPEN packet will negotiate BGP version、Holdtime, Router_id, optional parameter and so on; Generally due to failure to correctly identify the parameters, in particular the parameters of others informational firms;
4) MD5 authentication configuration errors;
5) Router-id conflicts；
6) The wrong configuration of BGP connection between Confederation and non-confederation;
7) Marker error, it appears rarely；
8) And so on;
