Deleted certs cause letsencrypt to fail

let me first begin by saying i was not intending to delete the certs but ended up deleting them.
anyway, without the certs i cannot issue certs for this domain or use the certs that existed. i cannot revoke them either since it requires the cert to delete.

interestingly, this also causes the client to fail:

2015-12-12 06:56:57, symlink /etc/letsencrypt/live//cert.pem for cert does not exist.
2015-12-12 06:56:57,742:DEBUG:letsencrypt.cli:Exiting abnormally:

probably worth reinstalling the LE script and clearing the /etc/letsencrypt folder as if starting from scratch.

I’d also then make sure you test with the test server, so you don’t hit the rate limits.

presume this is Testing Against the Let's Encrypt Staging Environment the test server.

i will try to clear it out and start over although i already it the rate limit trying to fix this.

Yes, that’s the test ( staging) server.

It doesn’t have the same limits, so is good for testing ( although the certificates are not recognised by browsers as trusted by default). They’re good for test purposes though.
