After the errors appear, the Horizon interface reports the following error:

Error: Failed to perform requested operation on instance "test", the
instance has an error status: Please try again later [Error: Exceeded
maximum number of retries. Exhausted all hosts available for retrying build
failures for instance 9f206d9f-6c96-479f-bbaa-116d967129dc.].

What could be happening? I believe I'm missing something to configure, but
I don't know where to start.
