ClamAv + Microsoft Azure VM: Cannot connect to daemon from other VM

I got two VMs on Azure that are in the same subnet. One VM (10.1.0.6) has clamav daemon running, the other runs a Java Wildfly Application (10.1.0.5).

I would like to send files from Java Application to the clam av daemon.

I checked that Clamav is running and listening on port 3310:

 netstat -ant|grep 3310
 tcp        0      0 127.0.0.1:3310          0.0.0.0:*               LISTEN
 
 netstat -lnp | grep clam
 (Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
 unix  2      [ ACC ]     STREAM     LISTENING     800631   -             
 /var/run/clamav/clamd.ctl

For the Clam Av server there are all inbound ports open within the virtual private network. However, if I check on the java server if the port is available via telnet or nc I get:

telnet 10.1.0.6 3310
Trying 10.1.0.6...
telnet: Unable to connect to remote host: Connection refused

nc -vz 10.1.0.6 3310
nc: connect to 10.1.0.6 port 3310 (tcp) failed: Connection refused

If I send files via Java Application I get the same error.

Is my clamav setup correctly and is this issue related to my Subnet configuration?

Thanks for your help!
