[SOLVED] Error when installing SSL Certificate with Let's Encrypt

I have had this problem in the past…ive unfortunately forgotten what the cause was.

  1. i would check to ensure your webserver permissions to the directory in question are correct

  2. Has the directory outlined in the error above actually been created? If not then that may help in the problem solving process.

  3. This may be a result of my inexperience, but can i throw it out there anyway…i note the URL in the error is http …shouldnt it be putting the challenge in https?

  4. Have you opened port 443 for https? (once again i dont know what error this throws in terms of the acme challenge passing)

  5. Are you running nginx? Is it configured to use the same directory as lets encrypt? https://community.letsencrypt.org/t/404-error-at-well-known-acme-challenge/44271/6

  6. These posts may be of help as it appears to throw same error as yours…https://community.letsencrypt.org/t/unauthorized-404-error-well-known-acme-challenge-on-a-hosting-web-space/55512/4
