Unable to renew cert after years of renewing with no problem

[JuergenAuer]

Hi @dgets

@dgets

    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -3] Temporary failure in name resolution

now your internal dns doesn't work.

So Certbot

@dgets

urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='ocsp.int-x3.letsencrypt.org', port=80): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f5afab426a0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution'))

can't check the OCSP-status of your certificate.
