ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 0

Question

I am getting the following error

ERROR 2013 (HY000): Lost connection to MySQL server at 
\'reading authorization packet\', system error: 0

Answer 1

I've struggled a lot with this error. Tried every single answer I found on the internet.

In the end, I've connected my computer to my cell phone's hotspot and everything worked. I turned out that my company's internet was blocking the connection with MySQL.

This is not a complete solution, but maybe someone faces the same problem. It worths to check the connection.

Answer 2

I solved this by stopping mysql several times.

$ mysql.server stop
Shutting down MySQL
.. ERROR! The server quit without updating PID file (/usr/local/var/mysql/xxx.local.pid).
$ mysql.server stop
Shutting down MySQL
.. SUCCESS! 
$ mysql.server stop
ERROR! MySQL server PID file could not be found! (note: this is good)
$ mysql.server start

All good from here. I suspect mysql had been started more than once.

Answer 3

If you get this when using DevDesktop - just restart DevDesktop!

Answer 4

I use several mysql connections (connecting to different sets of databases) in localhost.

This happened to me after I shut my computer down and mysql was not properly shutdown. After starting my machine I was able to successfully connect to multiple db connections except one (I used this a lot before my machine shutdown). As per the instructions in this posts I doubled connect_timeout but I was not able to connect to that one database connection.

I restarted my machine and i can successfully connect now. This will help you unblock yourself but it'd be great if it can be fixed without restarting the machine.

Another concern is: connection_timeout seemed to me delay related problem but I was getting the error immediately in localhost when there is no network in the equation.

Answer 5

I have a mac but would assume all linux are the same for this part...

In my case I got this:

2018-12-03 11:13:27 - Start server: 
2018-12-03 11:13:27 - Server start done.
2018-12-03 11:13:27 - Checking server status...
2018-12-03 11:13:27 - Trying to connect to MySQL...
2018-12-03 11:13:27 - Lost connection to MySQL server at 'reading authorization packet', system error: 0 (2013)
2018-12-03 11:13:27 - Assuming server is not running

I ran this:

sudo killall mysqld

And then started the mysql again through mysqlworkbench although in your case it might be like this:

mysql.server start

*sidenote: I tried running mysql.server stop and got this Shutting down MySQL .... SUCCESS! but after running ps aux | grep mysql I saw that it hasn't really shut down...

Another possibility can be connection reset from the TCP wrappers (/etc/hosts.deny and /etc/hosts.allow). Just check what is coming in from the telnet to port 3306 - if it is nothing, then there is something is in the middle preventing communication from happening.
