Solution 1

I suspect that when your laptop is on a "different network" that it is then inside the firewall that is also protecting the database servers you are connecting to. Hence, there is no problem making the database connections for this case.

Your "network at home" I presume is outside of the firewall protecting the database servers that you are trying to connect to. Hence, your database connection attempts for this case are being ignored due to the firewall protection.

If these assumptions are correct, you will need to contact the network administrator of the "different network" to gain access through the firewall from your home network.

I hope this helps.

Solution 2

Your problem is similar to https://youtrack.jetbrains.com/issue/IDEA-163324

The solution is:

open terminal
run scutil --getHostName
if hostname is not set or contains .local, run sudo scutil --set HostName "<YOUR HOSTNAME HERE>"

Solution 3

Please make your string url like below and add sqljdbc42.jar in your project

url = "jdbc:sqlserver://" +serverName + ":1433;DatabaseName=" + dbName +";

encrypt = true;

trustServerCertificate=true;

Solution 4

This exception also be present when your SQLJDBC driver jar is old .. for example if your SQL server is latest 2018 or 2019 then if you use old JDBC jar file like sqljdbc4.0 then you will get this exception

Solution for this would be take latest jar file to support 2018 or 2020 version .. i have used below jar file mssql-jdbc-7.2.2.jre8.jar to solve the issue. so look into this way as well

I'm having problems connecting to SQL databases. Whenever I try to connect to a SQL server I get the following error;

This is using com.microsoft.sqlserver.jdbc.SQLServerDriver

Whenever I use the JtDS driver (suggested by eg. this post), I'm still not able to connect to the SQL server and I get the following error.

The connection string I use: (using jtds)

jdbc:jtds:sqlserver://url.database.windows.net:[PORT];database=name;

OR when not using jtds..

jdbc:sqlserver://url.database.windows.net:[PORT];database=name;

I also have a server that is actually able to run and connect to the database using these configurations. I just keep getting these errors trying to connect to the database locally.

I am running macOS Sierra version 10.21

jtds version:

<dependency>
    <groupId>net.sourceforge.jtds</groupId>
    <artifactId>jtds</artifactId>
    <version>1.3.1</version>
</dependency>

sqlserver version:

<dependency>
   <groupId>com.microsoft.sqlserver</groupId>
   <artifactId>sqljdbc4</artifactId>
   <version>4.0</version>
</dependency>

EDIT:

I am able to connect to the database using the same configuration AND same laptop on a different network. It is only on my network at home that I get this error

I will try this later today and let you know if it worked, thanks!

Not actually what fixed my problem, it magicly went away after some time. Though, must be useful for anyone else having this issue.

Beware, problems that magically disappear without explanation can often reoccur.
