Embedding report fails after publishing app to Azure

[HeineSkov]

I'm using the Power BI Javascript library to embed reports in an Angular application. Everything works perfectly when I'm running on localhost. After I publish to an Azure App Service, all the reports fail with the error

"message":"LoadReportFailed","detailedMessage":"Get report failed","errorCode":"403"
The configuration for the embed function call

type: 'report',
id: this.reportId,
embedUrl: embedConfig.EmbedUrl,
pageView: "fitToWidth",
accessToken: embedConfig.EmbedToken.token,
tokenType: pbi.models.TokenType.Embed,
settings: {
filterPaneEnabled: false,
navContentPaneEnabled: true
}
};

Anything I'm missing in Azure? I don't understand why it's working when running on localhost but not in Azure

I also get this 403 error in the log when trying to embed a report
