Hello Community,
Environment : Private Cloud Administration Portal Version 4.2.6_202508291712 and Secure Endpoint v5.4.2025081121 , both the latest. Upon upgrade a dozen of the amp sensor from 8.4.3.30374 to version 8.5.0.30549 we had a significant increase of Cloud Query Failure Rate (https://www.cisco.com/c/en/us/support/docs/security/secure-endpoint-private-cloud/222842-troubleshoot-cloud-query-latency-and-clo.html), we created a TAC case and the final conclusion was because of the sensor version 8.5.0.30549 - was a faulty one (we couldn't uninstall\reinstalling to the previous one 8.4.3.30374 because of the production environment ).
Now after upgrading all the affected sensors from 8.5.0.30549 to 8.6.0.30578 it's still he same.
If you encounter any issue like this and you the the answer just let me know.
Thank you.
