Hello people
I have an environment with InnoDB Cluster with 05 knots.
Recently, one of my servers stopped connecting to my database and triggered the message:
SQLSTATE [HY000] [1129] Many connection errors of 127.0.0.1
After restarting the mysql router for this environment, the service was reconnected to the databases.
However, while parsing the MySQL Router Log for a while, I noticed the following message occurring several times:
2018-07-12 15:57:05 routing WARNING [7fccbb7fe700] Timeout reached attempting to connect to MySQL server HOSTNAME: 3306: Connection timed out
2018-07-12 15:57:14 routing INFO [7fccbb7fe700] [routing: mysqlclusterprd_default_ro] fd = 53 Previous authentication socket failed 127.0.0.1: client authentication has expired
I could not find anything that is causing this problem.
can you help me?
MySQL version: 5.7.22
Version of the MySQL Router: 8.0.11
