Hello everyone. First, my thanks to Let´s Encrypt and its team for great project and work.
I hope someone can help us with this issue.
Today, all our SSL from Let´s Encrypt stop working. The certificates are valid and have not expired yet. We had not ping to ocsp.int-x2.letsencrypt.org, ocsp.int-x3.letsencrypt.org, and ocsp.int-x4.letsencrypt.org. We tested our network and everything was working properly from our network side. This is the error we got:
[Wed Dec 21 11:58:34.643856 2016] [ssl:error] [pid 8506] AH01941: stapling_renew_response: responder error
[Wed Dec 21 11:58:54.670917 2016] [ssl:error] [pid 8498] (101)Network is unreachable: [client 184.108.40.206:57706] AH01974: could not connect to OCSP responder ‘ocsp.int-x3.letsencrypt.org’
So I wonder why this could happen that all our network was somehow banned from Let´s Encrypt server. This was not for certificate issuance.
The problem was that all the websites with Let´s Encrypt would load at all.
Datacenter provider, if applicable, is: Zam Ltda.
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): cPanel
Thank you so much.
