Aria Operations 8.18.x
The upgrade is unsuccessful due to excessive API requests sent to Aria Operations, resulting in repeated 429 (Too Many Requests) errors.
Analyze the /storage/log/vcops/log/suite-api/localhost_access_log.txt Log to identify the IP generating excessive API requests, temporarily block its calls, and then retry the upgrade.
