title: MySQL Replication: Waiting to reconnect after a failed registration on master
body: <p>I have two MySQL servers in a master-master setup. The setup is exactly the same (following the process I wrote last time) but is not working as expected.</p>
  
  <p>I am receiving the messages:</p>
  
  <p><code>Slave_IO_State: Waiting to reconnect after a failed registration on master</code></p>
  
  <p><code>Slave has read all relay log; waiting for the slave I/O thread to update it</code></p>
  
  <p><code>Slave_IO_Running: Connecting</code></p>
  
  <p>I recreated the replication user multiple times to no avail. If I use another user (in this case, admin, which has all privileges) things work fine.</p>
  
  <p>I can't find any reason that the user name would impact on the connection.</p>
  
  <p>Any ideas?</p>
