403 Access forbidden since Zephyr Squad add-on is not active

Hello,

I'm calling Zephyr APIs and all are returning same issue
example: https://prod-api.zephyr4jiracloud.com/connect/public/rest/api/1.0/executions

It was working but now it returned: 403 Access forbidden since Zephyr Squad add-on is not active. Current add-on status is PLUGIN_DISABLED

And When I use Zephyr through JIRA, it works normally.

What is the issue?

Thanks,
