Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: zimtstangl.de & www.zimtstangl.de
I ran this command: I tried to create the certificate via zerossl.com, I do (and did this in the past often), today all my domains were successful in creating a certificate via HTTP verification. But this single domain keeps to get the error when verifiying the temporaray files. The files do exist. They is a redirection set from port 80 to 443. I can access the files but it seems letsencrypt cannot for some reason. What could be the reason why letsencrypt can’t access my server?
In my apache logs I see the request coming to port HTTP 80 (which is redirected to HTTPS 443 (same url):
66.133.109.36 - - [11/May/2019:13:50:25 +0200] “GET /.well-known/acme-challenge/pWTXuX2M-dwlrjkT1h3ok9wkDADOR-HfT-gv75oZr98 HTTP/1.1” 301 671 “-” “Mozilla/5.0 (compatible; Let’s Encrypt validation server; +https://www.letsencrypt.org)”
But in the logfile from HTTPS, letsencrypt does not even try to GET the file.
It produced this output:
Fetching https://www.zimtstangl.de/.well-known/acme-challenge/AS5HW2tGYeAqVEYz9_3oS2WXrD7OYCJgj9v6MEsAcRU : Timeout during connect (likely firewall problem)
