Issue descriptionChrome Version : 55.0.2883.87 OS Version: 10.0 URLs (if applicable) : https://trello.com/1/... Other browsers tested: none (from Chrome extension) What steps will reproduce the problem? 1. Attempt a series of xhr requests (via jQuery), offset by an interval based on the total number of requests (~50 in my examples). 2. The first request (usually just the first, but have seen as many as 6, which has been difficult to reproduce) is stalled/canceled, while the second goes through the expected DNS lookup / initial connection / SSL cycle, then that and all subsequent requests in that group are successful. 3. The cycle is repeated at variable intervals (every 1 to 5 minutes) and the issue occurs intermittently, but with some regularity. What is the expected result? All xhr requests should be be successfully attempted. What happens instead of that? Some requests are stalled/canceled. Please provide any additional information below. Attach a screenshot if possible. Screenshots attached showing normal and canceled request behavior. Net internals log also included with canceled request and first successful request.

Could you provide a net-internals log? https://dev.chromium.org/for-testers/providing-network-details

My original post has a net-internals log in addition to the screenshots, did you need something additional?

It looks that the H2 stream is cancelled because the H2 session receives GOAWAY.

Indeed server sends a GOAWAY, with error code NO_ERROR. Request is on stream 93, and GOAWAY has last stream id 91. This means it is safe to retry the request on a new connection. Marking as duplicate of 681477. |
