Community pod failure for gpon equipment

Hi, after Björn had restarted ADTRAN OLT pipeline is running again, but with a lot of errors.
I see in sum two major issues: # Keyword 'Check IPv4 Address on DHCP Client' failed after retrying for 1 minute 30 seconds. The last error was: 'Device "eth1.7" does not exist.

1. Keyword 'Check Ping' failed after retrying for 1 minute. The last error was: 'ping: SO_BINDTODEVICE: Invalid argument.

Maybe both have the same root cause. Can you check, what is going wrong. I will check robot logs and keep you informed.
 
 
Some more info regarding issue 1.:
A SSH connection is etsablished but command 'sudo -s' failed due:
sudo: unable to resolve host SCOMA0302125: Connection timed out root@SCOMA0302125:~#
I do not understand, because time out is set to 50s:
index=46 host=10.34.90.41 alias=None port=22 }}{{timeout=50 seconds{{ newline= prompt=# term_type=vt100 width=80 height=24 path_separator=/ encoding=UTF-8 escape_ansi=False}}
Or am I wrong?
Anyway, that's the reason why following command ip address show eth1.7 failed. (edited)
