TestNet BlockExplorer Dependency

Technical
1

Hello,

I’d like to understand the dependency to issue a certificate in relation with the testnet.blockexplorer.

Since 3 ou 4 days ago, I can’t issue a new certificate in Bitcoin TestNet, due that error: testnet.blockexplorer.com | 521: Web server is down.

It’s mean that testnet bitcoin is down ? I don’t understand , because I’m able to generate credit from Faucet to my public address… so in my mind it can’t be off… to transfer credit…

Could someone help me to understand this ?

I’m getting the same thing.

I think if it’s really down, nobody is issuing certificate in testnet bitcoin, right ?

If my afirmation is true, maybe the cert-issuer should allow to setup a differente blockexplorer in config.ini…

Att,
Fernando.

I got it working after updating my cert-issuer folder to the latest from the GitHub repo. It still fails a couple times at the same part of the process but it eventually goes through. I was then able to look up the Tx id to verify it was issued.

have you tried updating to the latest version?
