[MS SQLServer] Cannot connect with instance specified

Hello,

When trying to connect to a Microsoft SQL Server, I cannot connect to all servers with instances.

I have 3, yet dbeaver can only connect to 1.

The other two try to connect, but fail after like 10 seconds with an error message.

JDBC URL looks like jdbc:sqlserver://value\instance:1433 Read-only Connection. Driver: Microsoft Driver Platform: Microsoft Windows 7 and Ubuntu 16.04 (I tested on both). Everything else is default (no proxy, no tunnel, no database/schema.

Error:

Nothing added in the ErrorLog though.

Yet, using Microsoft Sql Server Studio, I can connect just fine.

How could I try to find more logs about the request itself? As it’s working fine with Microsoft Studio (and I re-created the connection 5 times to make sure no typos), I’d like to understand what happens for 10 seconds while trying to connect, as it should be working just fine.

Let me know what I can do to help resolve this issue.

In my dbeaver are two different jdbc drivers: I could get it to work with the MS SQL Server / jTDS driver (Under driver properties I could insert a name after “INSTANCE”) but not the other driver, even though there is a instance name setting under driver properties as well.
