Got yome issues with install-letsencrypt-cert.sh-Script on a server runnig apache2 (most issues here aim on ngnix):
Challenge failed for domain my.domain.com http-01 challenge for my.domain.com Cleaning up challenges Some challenges have failed. IMPORTANT NOTES: - The following errors were reported by the server: Domain: my.domain.com Type: unauthorized Detail: Invalid response from http://my.domain.com/.well-known/acme-challenge/DBjQ6Z_XrDAr8a0YK3AeBETzVwxz6HYMaU6rd0Hs7pE [123.456.789.012]: "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN\">\n<html><head>\n<title>404 Not Found</title>\n</head><body>\n<h1>Not Found</h1>\n<p"
Followed Quick-Install Guide, everything seems to work pretty well (Domain ist reachable, working DNS A record). Except LE.
Any ideas? Thank for your effort!
PS: Debian Buster.
