Creation & renewal fail after upgrade from 1.7.0 to 1.9.0

Help
1

2 weeks ago i was using cerbot 1.7.0 (installed not from snap) and flawlessly create several virtualhost and valid letsencrypt. from then, i upgrade to certbot 1.9.0, i do not create any virtualhost until now, and then i notice that creation of new SSL from LE are broken, showing error below, as the DNS record doesn't valid, however the DNS record is valid. there is no problem when I create virtualhost from current domain on the another CentOS server with certbot 1.7.0. also the server already running certbot for 144 day, so i think there is problem with the latest certbot (1.9.0).

i'm planning to upgrade 1.10 using snap. but i'm going the explore more before upgrading since i'm not convinced that upgrading to 1.10 will solve the problem.

My domain is: teacher.e-ducare.id

I ran this command: cerbot --nginx -d teacher.e-ducare.id , cerbot renew

It produced this output:

Domain: teacher.e-ducare.id
Type:   unauthorized
Detail: Invalid response from http://teacher.e-ducare.id/.well-known/acme-challenge/gmpfgm3Sr6dHXy7vqLZjnkJhc_32KuHZ9ygknmeoGoo [128.199.96.58]: "<html>\r\n<head><title>404 Not Found</title></head>\r\n<body>\r\n<center><h1>404 Not Found</h1></center>\r\n<hr><center>nginx</center>\r\n"

To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address.

Hi @adinovic

that's not an upgrade-problem, Certbot doesn't understand your config.

What says

nginx -T

I'm not sure if it's nginx problem, but previously it works, i even use same vhost template. i've also tried to remove new vhost configuration.

Use your root, create the two subdirectories /.well-known/acme-challenge, there a file (file name 1234), then try to load that file via

http://teacher.e-ducare.id/.well-known/acme-challenge/1234

If that works, use that root as --webroot, see

thanks @JuergenAuer using
certbot --webroot -w /var/xxx/teacher.e-ducare.id/dist -d teacher.e-ducare.id
it does work. how do i renew the existing vhost? from renewal configuration, should i change the version and renewal params to use webroot as follow ?

   version = 1.7.0 -> 1.9.0
   [renewalparams]
    authenticator = webroot
    account = xxx
    webroot_path = /var/xxx/educare/teacher.e-ducare.id/dist,
    server = https://acme-v02.api.letsencrypt.org/directory
    [[webroot_map]]
    teacher.e-ducare.id = /var/xxx/teacher.e-ducare.id/dist`

or is it better to request new certificate with webroot?

6

Certbot should update the config file.

Or you have created a second certificate (001 / 002 etc.).

7

thanks. in the end i create all new certificate based on webroot then i can use normal certbot renew to renew all certificates. still have no clue why certbot nginx coincidentally break after upgrading to 1.9.0
