Issue certificate on testnet

Hi,

I am trying to issue certificate in testnet mode (bitcoin) and I have a local bitcoin node running on testnet mode.

I have copied the sample unsigned certificate from examples folder in cert-issuer to /etc/cert-issuer/data/unsigned_certificates.

Then issues the command cert-issuer -c /etc/cert-issuer/conf.ini
The command got success with below output:

I waited for hours,days but still i am not able to see my tx (ae26c88330c9a4500c98908b0da402c49aea786b92d03ca47209da1bdb5099c8)on the blockchain testnet explorer.

Any help would be very much appreciated.
