This error indicates that the request failed to send a message for the signed transaction and will remain in the Pending status until it is canceled.

This is typically due to a network issue. However, in one case we found that the DNS prevented the message from reaching the signing phase.

Resolution

To resolve this issue:

1. Go to the vi /etc/systemd/resolved.conf directory.
2. Under the Resolve heading, change the DNS value to 8.8.8.8 8.8.4.4.
3. Run the following command:

   systemctl restart systemd-resolved.service
