Ignition v8.0.9 (b2020021812)
Java: Azul Systems, Inc. 11.0.5

It recover itself after few seconds

Your gateway responded with an invalid HTTP response code, so the local designer threw that error. You can check if there’s anything in the gateway logs at the same time period (https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/119/0/obtaining-ignition-logs), but it could be a variety of things, including problems outside of Ignition; ie, a brief network hiccup.

Thanks @PGriffith, My intention with this post was like reporting a problem. I’ll check the logs, but what’s really surprising that this happened in a localhost.
