We have an ASP.NET project, made in .NET Framework 4.6, that uses the MySQL.Data nuget package, version 8.0.29. We have multiple MySQL databases in a cluster. The MySQL connector has functionality for adding multiple hostnames (comma separated) so that the traffic will be split between multiple databases. We tried using this and it seems to work fine on our test environment, but on production we are seeing many exceptions in the Event Viewer of the Windows Server. Production has, of course, much more traffic than the test environment, so that might be part of the cause.
These exceptions do not occur when we only use one of the database. We have tried all of them seperately and they all work without problem on production by themselves, just not together.
This is an example of our connection string:
server=example1.com,example2.com,example3.com;port=25060;uid=username;pwd=password;database=database;pooling=false;Allow User Variables=True;CharSet=utf8
(Pooling is set to false, because pooling is causing other problems for us which is a separate issue.)
Here are the errors we are getting:

Does anyone have an idea what is going on here? Is it something we're doing wrong?

MSSQL Error 'The underlying provider failed on Open'
(31 answers)
Closed last year.
I have the following piece of code, which works at a customer, but not on my computer:
var result = await db.Configurations.FirstOrDefaultAsync().ConfigureAwait(false);
db is derived from a System.Data.Entity.DbContext, defined in EntityFramework.6.4.0\lib\net45\EntityFramework.dll.
In the corresponding SQL Server database, there is a table "Configurations" and it contains an entry.
When I launch the line of source code, an Exception gets generated (I hereby show the slightly formatted content of the immediate window while asking ? ex):
? ex
{"An exception occurred while initializing the database. See the InnerException for details."}
Data: {System.Collections.ListDictionaryInternal}

I know this line of code works at customer's system, and I'm working on a restored backup of customer's DB.
What is going wrong and what can I do to fix it (what is the underlying provider)?
Thanks in advance
In the meantime the problem is analysed:
I had taken the backup of the customer's DB and restored it on my PC, but the username, as indicated in the connectionstring in source code, was wrong, hence my application could simply not open the database connection, so now the problem comes down on a database user management issue.
Thanks for all the support.
I got a fresh machine, with just Visual Studio 2015 and the latest .Net Framework, cloned a repository that accesses a remote Oracle 11g Database using Entity and Oracle.ManagedDataAccess from Nuget, this project does work in other machines,
I tested the remote connection using SqlDeveloper, and verified the port access with telnet and even created a simple and local Oracle Database to exclude any network related error
To confirm the error i created a simple Console Project following a Oracle Article and still got the same error
Exception : The provider did not return a ProviderManifestToken string.
InnerException : ORA-01017: invalid username/password; logon denied
I do not have any Oracle Client installed, and as far as i can tell i do not need any because i am using Nuget
And yes, i am extremelly sure of the user and password, as said above, the connection works when using SqlDeveloper
Oracle ManagedDataAccess Nuget

The exception is thrown when tests are run from VS Test Runner or from command line with mstest.
The Oracle Database tools in Visual Studio throws the same exception.
In application the Oracle ManagedDataAccess provider is used. Package version is 12.1.2400.
OS: Windows 10 Pro x64
An application locally published to IIS works just fine. There are no any problems with database connection.
Does anybody know how to fix this?
Thanks in advance!
Same problem here. Today I reopened a console application started in august and Oracle gave me the same exception.
Solved switching back to version 12.1.22 of Oracle.ManagedDataAccess from NuGet.
UPDATE 2016-12-27
Found final solution here: https://community.oracle.com/thread/3972810
The problem is caused by SQLNET.AUTHENTICATION_SERVICES set to NLS.
To solve the problem you have to edit app.config / web.config:
<oracle.manageddataaccess.client>
<version number="*">
<dataSources>
<dataSource alias="SampleDataSource" descriptor="(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL))) "/>
</dataSources>
<settings>
<setting name="SQLNET.AUTHENTICATION_SERVICES" value=""/>
</settings>
</version>
</oracle.manageddataaccess.client>
I added the <settings> section.
I've been using SQL Server Compact Edition 4.0 SP1 with Entity Framework for data access in one of our web applications for the past couple of years without problems, but in the last couple of days I've been getting errors when attempting to run the application locally from within IIS.
The error I'm getting is, unfortunately, not very helpful:
System.Data.SqlServerCe.SqlCeException: Unspecified error [ sqlcese40.dll ]
[EntityException: The underlying provider failed on Open.]
As I had just checked out a branch into a new directory, at first I thought the issue was caused by permissions, but granting the application pool read/write access did not fix it.
I tried a number of other things, uninstalling and reinstalling SQL Server CE etc... but this didn't fix the issue either.
Finally, I changed the "Enable 32-bit Applications" setting for the app pool to true and this "fixed" the issue and I was able to get the application running again.
I'm not satisfied with this solution however, as I've been running without this enabled for months without any problem and I want to figure out what has caused the issue but I'm a bit stumped as where to look next.
Just wondered if anyone had any suggestions?

I'm new to ASP.NET and finding connection strings very difficult to get to grips with.
I've been half successful with my connection of the 2 connection strings below, the connection string for the database security works fine, but I’m unable to get the main string dealing with the rest of the data to work. I think it must be because of the Entity Framework element of the connection string.
For the metadata part, I've used the res://*/ part as I assume this is less efficient but will catch all, if I've correctly understood the documents that I've been reading.
<remove name="ApplicationServices" />
<add name="ApplicationServices"
connectionString= "Server=184.168.194.64,1433;
Database= myASPNETDB;
User=****;
Password=****;"
providerName="System.Data.SqlClient" />
<remove name="PropManEntities" />
<add name="PropManEntities"
connectionString="Metadata=res://*/;
provider=System.Data.SqlClient;
provider connection string='Data Source=184.168.194.64,1433;

Try this
<add name="PropManEntities" connectionString="data source=184.168.194.64,1433;initial catalog=myTest_C;User Id=****;Password=****;MultipleActiveResultSets=True;App=EntityFramework" providerName="System.Data.SqlClient" />
Sorry, I didn't realize you're using edmx file..
try this version (instead of the ????? use your filenames) :
<add name="PropManEntities" connectionString="metadata=res://*/??????????.csdl|res://*/????????????.ssdl|res://*/???????????????.msl;provider=System.Data.SqlClient;provider connection string="data source=184.168.194.64,1433;initial catalog=MPInvoicingSystem;user id=*****;password=*****;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
If this is not working, I'd suggest you to add a new edmx model and copy the connection string automatically added.
