Erro na tag parent do pom.xml

Boa tarde pessoal tudo joia? Estou com problemas na tag do pom.xml do projeto. Vamos aos passos: 1- Baixei o apache maven e adicionei na environment var PATH, também testei o comando mvn -v para testar o funcionamento. 2 - Importei o projeto do fórum Alura e importei no eclipse como um Maven Existing Project. 3 - Concluido o import o pom.xml já começa apresentando o erro a seguir:

Project build error: Non-resolvable parent POM: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.1.4.RELEASE from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.1.4.RELEASE from/to central (http://repo.maven.apache.org/maven2): Failed to transfer http://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.1.4.RELEASE/spring-boot-starter-parent-2.1.4.RELEASE.pom. Error code 501, HTTPS Required and 'parent.relativePath' points at no local POM.

4 - Pesquisei aqui no fórum e ja tentei executar o comando mvn -U clean install de dentro da pasta do projeto e dar um upgrade no projeto dentro do Eclipse, porém sem sucesso, o erro persiste. 5 - Pesquisei no Stack Overflow e também adicionei as tags no pom.xml mas também nâo obtive sucesso.

ps.: não consigo subir o projeto por conta deste erro no pom.xml.

Segue abaixo o código do meu pom.xml.

Peço que se possivel me auxiliem com esse erro porque ja tentei tudo que eu conheço e não estou saindo do lugar.

Obrigado.
