Hello, I’ve been having problems with Percona 5.7 (Server version: 5.7.18-15-log Percona Server (GPL), Release ‘15’, Revision ‘bff2cd9’) and MHA 0.57. I setup MHA and everything looks right, but when I start the MHA Manager, I get connection errors:

root@db-perc-02:~# masterha\_check\_repl --conf=/etc/mha/app1.cnf  
[…]  
MySQL Replication Health is OK.

root@db-perc-02:~# masterha\_manager --conf=/etc/mha/app1.cnf

So it loses the connection to the other server, but the ping is ok. On the other server there are some errors:  
2017-06-27T14:16:22.598621Z 16 [Note] Aborted connection 16 to db: ‘unconnected’ user: ‘mhauser’ host: ‘172.16.11.226’ (Got an error reading communication packets)

But the strange thing is that if I just change Percona server, for MySQL Server 5.7 and run the exact same configuration, MHA works perfectly. Any ideas?
