TYPO3 9 LTS Version 9.5.5 - Could not access remote resource https://repositories.typo3.org/mirrors.xml.gz - typo3

Question

I am working with the current version Typo3 9.5.5, with PHP version: 7.3.2 and XAMPP 3.2.3 on Windows 7. In the backend interface under ADMIN TOOLS -> Extensions -> get preconfigured distributions I always get the error "Could not access remote resource https://repositories.typo3.org/mirrors.xml.gz.". I have tried it with https://www.pagemachine.de/blog/wie-ihr-typo3-8-0-als-locales-testsystem-unter-windows-installer-unser-tutorial/#div-comment-4718 but unfortunately did not work. Does anyone have a solution?
[Edit] I would like to upload the whole file php.ini, but unfortunately I have not found a way to do this. It is not possible to put all the content of the php.ini here, because the character limit is 30000. I could just show the uncommented lines, but that would not be nice either.
A part of the C:\xampp\php\php.ini:
extension_dir="C:\xampp\php\ext"
;...
;...
;...
; When the extension library to load is not located in the default extension
; directory, You may specify an absolute path to the library file:
;
; extension=/path/to/extension/mysqli.so
;
; Note : The syntax used in previous PHP versions ('extension=<ext>.so' and
; 'extension='php_<ext>.dll') is supported for legacy reasons and may be
; deprecated in a future PHP major version. So, when it is possible, please
; move to the new ('extension=<ext>) syntax.
;
; Notes for Windows environments :
;
; - Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+)
; extension folders as well as the separate PECL DLL download (PHP 5+).
; Be sure to appropriately set the extension_dir directive.

Answer 1

You need to activate curl in your XAMPP installation. Maybe this Stack Overflow post can help you with that.
If you have Windows 10 Professional I can highly recommend DDEV-Local which gives you a solid base for local development. It should also work with Windows 10 Home.
In case you need help with DDEV, the #DDEV channel in TYPO3 Slack is very helpful.

Answer 2

I solved the problem by adding
(1) the line "extension = php_curl.dll" in the module settings part
and by updating
(2) the file "curl-ca-bundle.crt" in the line ; curl.cainfo = "C: \ xampp \ apache \ bin \ curl-ca-bundle.crt "does not exist in the Xampp directory (including subdirectories). Therefore, download the file "cacert.pem" expilicitly (just google) and replace the line ; curl.cainfo = "C: \ xampp \ apache \ bin \ curl-ca-bundle.crt" with curl.cainfo = "C: \ xampp \ cacert.pem ". Put the "cacert.pem" file in the directory "*C: \ xampp *".
(3) Also replace the line: openssl.cafile = "C: \ xampp \ apache \ bin \ curl-ca-bundle.crt" with openssl.cafile = "C: \ xampp \ cacert.pem". It should work then.
