@mwittig The pimatic-daemon.log shows only what I showed in the last post. This error log repeats on every request as long as the host is unreachable. If this takes longer pimatic hangs after - lets guess - about 20 unsucessful requests. What I am also wondering is, that there are no times stamps before the log lines. Here a bit longer excerpt:
15:28:46.651 [pimatic-shell-execute] error:>
Unhandled rejection Error: Command failed: /bin/sh -c sudo bash /home/pi/openv/vclientProxy.sh ...
Unhandled rejection Error: Command failed: /bin/sh -c sudo bash /home/pi/openv/vclientProxy.sh ...
Unhandled rejection Error: Command failed: /bin/sh -c sudo bash /home/pi/openv/vclientProxy.sh ...
### and so on until it hangs
When I call the script manually it returns with
