Unable to connect to local MariaDB on Linux (GTK)

In the past I used the Windows portable version through Wine on my Linux notebook (currently Ubuntu 24.04 with KDE) which worked very well. Today I noticed that there are several native builds for Linux as well.

So I tried the GTK version 12.28.1.1 which starts and I was able to import the settings from my old version. But unfortunately, I cannot connect to my local MariaDB instance. You can see the settings for that connection in the attached screenshot. When I try to connect I get an error popup saying:

Can't connect to local MySQL server through socket '' (111)

Do I have to change the old settings to make it work with the GTK version?

I would at least try to use a libmariadb if the drop-down provides it. Apart from that I see nothing wrong in your screenshot. Probably prefer 127.0.0.1 over localhost?

When I try it with the other lib, the same error occurs. And in the error popup it suggests using libmysqlclient.so.21 :-)

But changing from localhost to 127.0.0.1 did it!!

Thanks for your quick response.

Best regards, Ralf.
