Getting a "version unknown" error

[ChrisMpitzios]

Hi, we are getting a "version unknown" error when trying to perform
bundle exec stf-client -t $1 -u http://$2 connect -fnotes:marathon --all -v verbose
any ideas?

[Malinskiy]

Can you please post the stacktrace?
Thanks

The error log here describes that the devices you're trying to connect are unable to pass basic adb shell command execution test.
Can you double check that adb shell actually is responsive? Your devices might not work or the transport layer can be broken. I'd start by verifying if device is actually responding to adb commands

Finally, the main reason for this issue was network issues from our side (and bundler incompatibilities since you declare 1.16.a).
More specifically the machine running the stf server lost its ipv4 and this caused stf-client to be unable to connect to it. The point is that i tried to resolve it as ipv6 and retried to connect to it but this did not seem to work (for some reason i think stf-client does not like ipv6). After restoring ipv4 i retried and received the same error 'version unknown' which did not make sense and then i tried to remove
-v verbose
and it worked so apart from the ipv4 issue my command syntax may be wrong or the v argument may be not working
