Connection Lose Situation

[mercan01]

Hi all,

I have a system that contain 2 mx250 and  over of 400 branch connect to the hubs. Too control the WAN  I use Firepower.

However some of my branches when connect the hubs  and want to access the my sql  server their connections are breaks off. 

The other branches can connect clearly.

How can i fix this stuation?

Many thanks for help.

Are they all running the same firmware ?

Would probably be a good idea to take a packet capture and try to simulate the issue. That way you will be able to see if it is a connection reset or not.

Are the branches using all the same hardware. Are you able to find a pattern in the branches with issues i.e. similar model / firmware etc.
