My file Settings.xml, is normal

What can it be ?

The network has no proxy.

Your settings.xml is pointing to http repositories, this protocol is no longer accepted by the central Maven, only https for security reasons, probably was only working before because you had already downloaded. Change this line here:

          <repositories>
                <repository>
                    <id>central</id>
                    <url>http://repo.maven.apache.org/maven2</url>
                    <releases>
                        <enabled>false</enabled>
                    </releases>
                </repository>
            </repositories>

for

               <repositories>
                    <repository>
                        <id>central</id>
                        <url>https://repo.maven.apache.org/maven2</url>
                        <releases>
                            <enabled>false</enabled>
                        </releases>
                    </repository>
                </repositories>
