Renew certificate verification failed after delete certification

Help

Hi @sadeshwar94 welcome to the LE community forum :slight_smile:

There are a few things that can be improved.

  1. certbot 0.27.1 can be updated - the latest version is now 1.20.0
  2. The site isn't serving a chain:
    openssl s_client -connect gitlab.gpms.jp:443 -servername gitlab.gpms.jp |head
    depth=0 CN = gitlab.gpms.jp
    verify error:num=18:self signed certificate
    verify return:1
    depth=0 CN = gitlab.gpms.jp
    verify return:1
    CONNECTED(00000005)
    ---
    Certificate chain
     0 s:CN = gitlab.gpms.jp
       i:CN = gitlab.gpms.jp
    ---
  1. On this system, was certbot ever installed using pip?
    If so, that may need to be reverted.
