What could I do? Thank you.

Answer 1

I've been attempting to recreate your error but haven't been able to. It seems that configtxgen is successfully creating a genesis block for your channel, however osnadmin cannot join the first orderer to the channel.
Can you provide more context to your question? What version of Fabric are you using? Have you messed with any of the configuration yaml files in the test network?
If you are simply trying to run the test network tutorial, you can always wipe your local repositories and fetch the newest versions of the fabric and fabric-samples repositories then try again. Also, this link might be of use for helping you understanding the updated, "system channel-less" way of how the configtxgen and osnadmin binaries work together to create an application channel.
