build failed: SVN requires authentication

Hi all!
I'm a newbie to TeamCity and I'm using latest version 8.0.3 (build 27540). I really could not build my project, because TC server won't connect to my SVN server, which is configured to run through apache on linux.
When I'm trying to test connection, specifying url, username and password, which i can use successfully in TortoiseSVN on build server, i'm getting following error:

Test connection failed in <VCSName> :: default. svn: E170001: Authentication required for '<https://<svnserverip:port>> Subversion Repository'

And in server log
