MIQ does't update Ansible Tower provider

I have a problem synchronizing the provider Ansible Tower
Initially everything worked stably, but at one point it stopped refreshing the provider.
But at the same time, miq can continue to work with old templates, there are no error messages in the logs and there are no messages about the start of the refresh in general.
I added a new provider, but it also could not sync with it
Can someone help with this or suggest what can be done?

I also saw several similar thread , but they all remained without a solution
