Azure Healthcare Bot not accessible

Hello Noman,

You're encountering this message from the Azure Health Bot:

"I am sorry, I am no longer available to interact with you. Please try again later or contact support" despite it working fine for 15 days.

This message is not generated by your authored bot scenario but by the platform itself when it determines that the bot can no longer function within the constraints of your subscription.

The F0 plan is designed primarily for evaluation, offering only a limited number of sessions per month. According to the Azure Health Bot pricing documentation, the free tier provides only a small number of messages, and once that quota is exhausted within a billing cycle, the service may suspend interaction until the cycle resets. This reset usually occurs monthly.

Simultaneously, it's important to ensure that your Azure subscription is still active. For instance, if you’re using a free trial or a Microsoft Learn sandbox, these subscriptions may expire or be suspended, affecting all resources deployed under them—including your healthcare bot. You can inspect the status of your subscription by navigating to your Azure Subscription page. A suspended or disabled subscription will restrict access to your Health Bot service.

Another angle to consider is service degradation or outages, especially if your bot is deployed in a region experiencing temporary unavailability. Microsoft provides a real-time Azure Service Health dashboard, which you can use to identify if there are issues affecting the Health Bot or its dependent services in your region.

Sometimes, issues may not be related to quotas or outages, but rather to scenario errors or misconfigurations. If you've recently edited your bot's logic—perhaps changing a scenario flow, authentication mechanism, or channel settings—these changes might lead to broken responses or unhandled errors. It's advisable in such cases to test your bot using the built-in testing tools within the Health Bot management portal, starting with simple interactions like “hello” to isolate the issue.

If all diagnostic steps point toward a usage cap or subscription issue, and if your use case demands ongoing availability, it is highly recommended to upgrade from the F0 plan to a standard plan (S1 or higher). Upgrading not only removes usage limits but also grants access to production-grade capabilities such as SLA guarantees, security features, and increased support options. You can perform the upgrade directly from your Azure Portal or consult the official pricing guide for plan comparison.

Should none of the above resolve the issue, Microsoft encourages you to file a support request via Azure Help + Support. This allows a support engineer to investigate whether your bot instance encountered an internal platform issue or was unintentionally restricted.

Hope this helps, do let me know if you have any further queries.

Thank you!
