Adding [email protected] to Wants and After to my /etc/systemd/system/blitzapi.service systemd-Unit helped.
Now the API is working after restarting my node. No more toaster and errors in blitzapi.service.
Maybe [email protected] is doing something with the network-system of linux and than interrupts the API service.

sudo systemctl restart blitzapi after unlocking the wallet, gets the API up and running again.
Okay, here some logs, where the API get stuck after a fresh restart:

The Toaster at the top right displays the status The UI gets from The blitzAPI which in turn gets it from the raspiblitz.
So looks like an issue that LND or at least the RPC service is not starting.
@rootzoll @fusion44 any ideas?
