From below S1AP Trace after integrating a new eNB to the network, the MME is responding with S1 Abort response and the cause is: User initiated.

Dear, what is S1 setup response detail?

I can see abort message from both MME and eNB sides.
Please share S1 setup response nessage detail.

It’s on SCTP layer.
Please involve Transport team.
And can check MME, and node end SCTP parameters.

Do you have assigned BWP logs also?

At some point the S1AP is successful but then aborts.
