Alias inside VirtualHost is not working and gives 404 error - apache

Question

I have a server which maintains multiple domains using VirtualHost and I'm trying to setup GitWeb according to Gitweb - ArchWiki.
According to the wiki, I have to append the lines below to an Apache config file.
Alias /gitweb "/usr/share/gitweb"
<Directory "/usr/share/gitweb">
DirectoryIndex gitweb.cgi
Options ExecCGI
Require all granted
<Files gitweb.cgi>
SetHandler cgi-script
</Files>
SetEnv GITWEB_CONFIG /etc/gitweb.conf
</Directory>
After this, Alias works and I can access the service by accessing one of
192.168.10.102/gitweb/ (local IP)
https://my_domain_1.com/gitweb/
https://my_domain_2.com/gitweb/
...
So far, everything's okay.
Now I'd like to limit the effect of the Alias to one domain: my_domain_1.com. So I moved the lines above inside its existing VirtualHost settings.
<VirtualHost *:80>
DocumentRoot "/var/www/html1"
ServerName my_domain_1.com
# The lines are pasted here.
RewriteEngine on
RewriteCond %{SERVER_NAME} =my_domain_1.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} END,NE,R=permanent]
</VirtualHost>
However, when I access https://my_domain_1.com/gitweb/, 404 error occurs. The error log says nothing and I have no .htaccess for the domain.
How can I make it work?

Answer 1

I found the solution.
Since I requested that all of http requests should be redirected to the https versions, I should have written the gitweb settings not in <VirtualHost *:80> (http) but in <VirtualHost *:443> (https). The result should be
<VirtualHost *:443>
DocumentRoot "/var/www/html1"
ServerName my_domain_1.com
# The lines are pasted here.
SSLCertificateFile /etc/letsencrypt/live/my_domain_1.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/my_domain_1.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
Now it works perfectly.
