Do you use some kind of firewall or packet filter? saned uses a
separate port for data (similar to ftp) and it seems that no data can
be transferred using that port.

To be sure that it's not a problem with the umax backend you can use
the test backend (scanimage -d net:ip_address:test -T).

Otherwise send debug logs of the client and server side:

Client:

SANE_DEBUG_NET=255 scanimage ....

Server:
SANE_DEBUG_UMAX=255 saned -d128

Bye,
