Maven can't resolve Active Object:Plugin Dependency for Confluence Plugin

Here is what I have tried:

<dependency>
            <groupId>com.atlassian.activeobjects</groupId>
            <artifactId>activeobjects-plugin</artifactId>
            <version>3.0.0</version>
            <scope>provided</scope>
</dependency>

Every other dependency works just fine.

Here is the error message:

[ERROR] Failed to execute goal on project statPlugin: Could not resolve dependencies for project com.tdk.plugin:statPlugin:atlassian-plugin:0.0.3: Failed to collect dependencies at com.atlassian.activeobjects:activeobjects-plugin:jar:2.0.0: Failed to read artifact descriptor for com.atlassian.activeobjects:activeobjects-plugin:jar:2.0.0: Could not transfer artifact com.atlassian.activeobjects:activeobjects-plugin:pom:2.0.0 from/to atlassian-public (Index of maven-external/): Connect to maven.atlassian.com:443 [maven.atlassian.com/18.184.99.150, maven.atlassian.com/18.184.99.149, maven.atlassian.com/18.184.99.151] failed: Connection timed out: connect → [Help 1]

The problem was the proxy, I just switched to another network and this solved the problem.
