[Nightly] Requests fail to load
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20170902220453 Steps to reproduce: I just go to a website (i.e. https://duckduckgo.com, or https://mozilla.org). Actual results: The request sometimes fails. I reload and i either have a failed TLS handshake, either another request, either the page loads normally (more frequent, by the way). (I had no problems with FF 55) (Kernel: 4.9.0-3-amd64, Debian 9.1) Expected results: The page should load normally at first try.
Hi Antoine, Could you help us to diagnose this by reproducing and gathering some logs? Instructions here: https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging#Using_aboutnetworking
[Tracking Requested - why for this release]: It is important to figure out why page loads some times fail. This looks like something new that only appeared on Nightly 57.
I just got back from PTO, I will try to get to this today, I have couple of bugs with similar priority. If someone have time please take a look.
Antoine, do you remember which page was failing? Can you still reproduce with newest Nightly? Can you try to change pref "network.tcp.tcp_fastopen_enable" and retry (open a new tab and type about:config, then search for network.tcp.tcp_fastopen_enable and change value from true to false or vice versa)?
Hello, It seems like I don't have this bug anymore. Antoine.
From the log I only see that some connections are reset by the server. I do not know know why. On this connection TFO was used, I am not sure if that has an effect. I think not since TFO was on for longer time before this bug is reported. I will closed this bug as worksforme. We can reopen it if it appears again.
