{ "type": "urn:acme:error:malfor med", "detail": "No such challenge", "status": 404 }



I made auto cert issuing program using letsencrypt.
then I found that one of sites has error on certificate.
When I see log, there was this.

{“time”: “2016-10-31 16:09:08”, “result”: “false”, “progname”: “httpGetSSL.sh”, “status_code”: “SSL_001”, “description”: “www.bii44.com:Verify error:{ “type”: “urn:acme:error:malformed”, “detail”: “No such challenge”, “status”: 404 }”, “line_num”: “181”}
{“time”: “2016-10-31 16:29:14”, “result”: “false”, “progname”: “httpGetSSL.sh”, “status_code”: “SSL_001”, “description”: “www.bii44.com:Verify error:{ “type”: “urn:acme:error:malformed”, “detail”: “No such challenge”, “status”: 404 }”, “line_num”: “181”}
{“time”: “2016-10-31 16:49:08”, “result”: “false”, “progname”: “httpGetSSL.sh”, “status_code”: “SSL_001”, “description”: “www.bii44.com:Verify error:{ “type”: “urn:acme:error:malformed”, “detail”: “No such challenge”, “status”: 404 }”, “line_num”: “181”}
{“time”: “2016-10-31 17:09:11”, “result”: “true”, “progname”: “httpGetSSL.sh”, “status_code”: “SSL_003”, “description”: “Certification for www.bii44.com is succefully issued. That cert’s enddate is 2016-10-31.”, “line_num”: “1228”, “end_date”: “2016-10-31”}

Then, can you see the problem? last success issuing cert’s enddate is 10-31.
and the cert file’s length was so short.

I want to know why it is happen and how can I prevent this problem.



I suspect this was related to an problem on the letsencrypt server - https://letsencrypt.status.io/pages/incident/55957a99e800baa4470002da/5816da347170c62119001f43 (which is why you were getting the malformed error at that time).

As to the end date, you would need to check with the author of your script - you :wink: check the file itself and see what the real enddate is for that certificate…


thank you for fast reply.
Maybe I have to check letsencrypt.status.io when this malformed error recur.
