[EW_7.10] Getmenu: suddenly got "nothing in server".

[El Berto]

Hi to all!
I have EW ver. 7.10-64 bit running since about 2 years on Ubuntu. Working correctly for all time.
Last wednesday I got "nothing in server".
Sniffring and sniffwave telling me data is correctly flowing, debug levels of wave_server tell me indexes are correctly updated.
Server IP address was 127.0.0.1, now I changed to 192.168.1.2 and I got it working again.

I had similar issue on CentOS, due to firewall rules.
Maybe a linux/ubuntu automatic update?
Thanks.
