Unable to download spring boot dependencies, spring repo asking for credentials

Question

Unable to mvn clean install spring boot project. Downloading dependencies failing with error Authentication failed for https://repo.spring.io/plugins-release/org/jetbrains/kotlin/kotlin-bom/1.3.50/kotlin-bom-1.3.50.pom 401 Unauthorized

Same POM and maven configurations worked earlier. All of a sudden facing this issue. Directly accessing the said repo is asking for credentials(attached image). Not sure how to proceed. Any help is much appreciated.

Note : Using https not http. Just a thought. If it related to version upgrading(if older version are not being supported) many such internal dependencies are failing how to handle this.

Answer 1

Changing mirror in settings.xml from SpringRepo to UK Central worked. Used below mirror

   <mirror>
      <id>UK</id>
      <name>UK Central</name>
      <url>https://repo.maven.apache.org/maven2</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
