failed to create x509 verify options from orderer config

Error message

failed to create x509 verify options from orderer config

What it means

Consenter.IsChannelMember wraps a failure of createX509VerifyOptions(oc): x509 verify options (root CA pool and intermediates) could not be constructed from the orderer config's certificates, so consenter TLS certificates cannot be verified.

Solutions

1. Check that all consenters' TLS certificates in the channel config are valid X.509 certs
2. Re-add properly issued TLS certificates for the consenters
