Hi Folks
Even in 8.0 I have still problems with my central mysql database on the ODROID C2.
I did some small investigations and it seems to be a boot sequence problem (at least what I found).
I have the "wait for network" activated in libreelec settings (with various delays up to 100000 seconds )
But it seems that the network adapter gets activated twice during boot (at least the network leds stop blinking while libreelec starts and restart blinking after a second).
It is not a general problem, since I was able to connect my running ODROID C2 to mysql by simply:
ssh'ing to the ODROID and entering "systemctl restart kodi"
So maybe my findings help you to fix the issue permanently
TNX in Advance, CU Frank
