Reading from stream failed - mysql_native_password error

Question

I have been facing the following error intermittently.

Answer 1

This issue is caused by Ssl.

Solution 1: SSL is not required. Since it is caused by SSL, we can turn off SSL by appending "SslMode=None" to the connection string.

Solution 2: SSL is required, server identity is important and needs to be verified. The server needs a internet connection to do the cert verification. Please note the crypto API doesn't update CTL for every process. The CTL is maintained at operating system level. Once you connect the server to connect and make an SSL database connection to the server, the CTL will be updated automatically. Then you may disconnect the internet connection. Note again the CTL has its expiration date and after that the Windows needs to update it again. This will occur probably after several months.

Solution 3: SSL is required but the server identity is not important. Typically SSL is only used to encrypt the network transport in this case. We can turn off CTL update:

Press Win+R to open the "Run" dialog Type "gpedit.msc" (without quotes) and press Enter In the "Local Group Policy Editor", expand "Computer Configuration", expand "Administrative Templates", expand "System", expand "Internet Communication Management", and then click "Internet Communication settings". In the details panel, double-click "Turn off Automatic Root Certificates Update", clickEnabled, then click OK. This change will be effective immediatelly without restart.

Guys I tried this: "SslMode=None" in the connection string, but if you need SSL then read this: http://www.voidcn.com/article/p-phfoefri-bpr.html

here is a sample connection string that works:

connectionString="Server=192.168.10.5;Database=mydata;Uid=root;Pwd=****;SslMode=None" 

Hope this helps

I had the exact same problem performing the upgrade on a windows form application. The solution I found was to change the server, because that one was in trouble. On the server that was presenting the similar situation you described had installed WordPress with MYSQL 5.6.34, on the other I did a clean install with MYSQL version 5.6.26.

I don't know if it has to do with the environment variables used. I believe it has nothing to do with Connection Timeout, if it is a property that is used only with the open connection. This error occurred in a shared environment as well as in a local installation with Maria DB. Another problem I found was that one of the selection commands that retrieved the data was having a problem in its formation not respecting the blanks:

SELECT COLUNA1, COLUNA2 FROM TABLE;

I made the change to SELECT COLUMN1, COLUMN2 FROM TABLE;

I am still testing on this solution I presented, and as of the time of posting there were no more errors.

Answer 4

I was getting the error

Authentication to host 'localhost' for user 'root' using method 'mysql_native_password' failed with message: Reading from the stream

I solved it when I put SslMode=None in my connection string.

However, I checked that the message is different from you

Check my connection

connection.ConnectionString = "server=myadressserver;userid=myuser;password=mypassword;database=test;SslMode=None";

I've been getting this error, quite frequently with Amazon's MySQL RDS instances. And most multi-AZ instances.

• It would be interesting to compare notes to see if others mostly get this issue with RDS also?

Amazon is known to rely heavily on "fast" DNS changes to switch over stuff with things like ELBs. I wonder if the same thing is happening with RDS? Or some other internal AWS switching is messing up the idle connections in the pool.

This would explain why the Oracle devs can't reproduce it and don't see it as much of an issue.

Anyway I've had to just deal with it and add retry logic when opening a connection.
