i have an urgent problem on every server where i'd updated the phpswitcher to 5.0.5.
On every server Let's Encrypt 3.5.0 is running too.
Now the first cert upgrade had failed
- Failed authorization procedure. my-domain.tld (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://my-domain.tld/.well-known/acme-challenge/xClGDXgN7miGD7hafNVtaUjmjSgs7nsX-9Ijt35yTKI [2a01:4f8:c010:41db::1]: "<html>\r\n<head><title>404 Not Found</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>404 Not Found</h1></center>\r\n<hr><center>" at /var/www/imscp/gui/plugins/LetsEncrypt/backend/LetsEncrypt.pm line 832.
I'd tested to open a file under the folder
But i got an 404 too. The webspace is empty and no htaccess which can protect this folder.
I'd tried this test on some other server with different domains and everytime the same.
If i change the folder to ".well-known/acmechallenge" i can reach the file without an error.
Do you have an idea to fix this problem?
