Resolved Alert: Mon, October 7, 2024 10:20 am
Initial Symptoms
Intermittent reports of users receiving an “ERR_HTTP2_PROTOCOL_ERROR” when trying to log in or pull report data.
Root Cause Analysis
Cause
From vendor:
Firewall maintenance was recently completed to prioritize HTTP/2 connections for performance purposes. Certain versions of the Google Chrome browser were having difficulty establishing connection via HTTP/2. In this scenario, browsers should fall back to HTTP/1.1, yet that was not occurring successfully for many users running Google Chrome.
Resolution
Given the popularity of the Google Chrome browser, TeamDynamix has disabled HTTP/2 until further analysis can be performed.
Prevention
Vendor is monitoring the issue.
