Stats Socket Issue haproxy -v 2.0.26

Hi people,
I know it’s almost time to celebrate the new year’s eve :slight_smile: but I’m having issues with the stats socket.
After upgrading Haproxy from 2.0.22 to 2.0.26 suddenly the stats are not available.
The cluster in question is made by 2 nodes. I updated only the passive one to version 2.0.26.
The one with version 2.0.22 is still exposing statistics, the other one doesn’t.
Here is the configuration, same for both of them:

log local0

nbthread 2

maxconn 100000

Hope anyone can help me :slight_smile:
Thank you in advance.
