I've had certbot setup for a couple of months for managing my certificates, one of my certificates was recently replaced on 24-01-2018,
but now I'm getting a errors when it tries to replace my cert: (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from , my permissions on the directories are correct and my DNS entries were working with it when I first set it up. When I check the certbot logs I see a traceback call: Traceback (most recent call last): File "/usr/bin/certbot", line 9, in <module> load_entry_point('certbot==0.20.0', 'console_scripts', 'certbot')() File "/usr/lib/python2.7/site-packages/certbot/main.py", line 861, in main return config.func(config, plugins) File "/usr/lib/python2.7/site-packages/certbot/main.py", line 786, in certonly lineage = _get_and_save_cert(le_client, config, domains, certname, lineage) File "/usr/lib/python2.7/site-packages/certbot/main.py", line 80, in _get_and_save_cert renewal.renew_cert(config, domains, le_client, lineage) File "/usr/lib/python2.7/site-packages/certbot/renewal.py", line 297, in renew_cert new_certr, new_chain, new_key, _ = le_client.obtain_certificate(domains) File "/usr/lib/python2.7/site-packages/certbot/client.py", line 318, in obtain_certificate self.config.allow_subset_of_names) File "/usr/lib/python2.7/site-packages/certbot/auth_handler.py", line 81, in get_authorizations self._respond(resp, best_effort) File "/usr/lib/python2.7/site-packages/certbot/auth_handler.py", line 138, in _respond self._poll_challenges(chall_update, best_effort) File "/usr/lib/python2.7/site-packages/certbot/auth_handler.py", line 202, in _poll_challenges raise errors.FailedChallenges(all_failed_achalls) Anyone else here using certbot and been running into this problem?
