miniDLNA/Network Shares not accessible after not using it for some time

miniDLNA server is not accessible after not using it for some time and I have to resave its settings to make it available again for my LG TV again or VLC at my computer. Could the hd-idle be a problem?

It is the same with “Network Shares” when I try to connect to Samba from another device after some longer time.

I found about “Notify interval” in miniDLNA settings. Is there something like that for Samba? Thanks.
