Hello, As of recently, shortly after updating nginx to version 1.11.0, we started getting the following errors in the error log for our sites configured with HTTP/2 and SSL: 2016/04/29 14:54:12 [info] 22321#22321: \*290 client sent stream with data before settings were acknowledged while processing HTTP/2 connection, client: XXX.XXX.XXX.XXX, server: 0.0.0.0:443 This is so far only happening when browsing pages with Safari (9.1) and only during a POST event. Safari displays an empty white page with an error message “Safari Can’t Connect to the Server”. Our observations so far are that this happens after some time of inactivity, which leads me to believe that some kind of timeout has occurred (keepalive\_timeout comes to mind). We have the following keepalive settings in nginx.conf: http { keepalive\_timeout 75s; } But this issue has never occurred before. Any feedback/help is appreciated!

Sorry, this is version of nginx obtained directly from GIT master branch. I believe in the sense of described behaviour, it is essentially the same as 1.10.0.

This issue should be reported to Safari. It appears that it doesn’t handle refused streams. I’m going to make a workaround, but it will take time. wbr, Valentin V. Bartenev ---

Thank you Valentin! Let me know when the workaround is in the trunk so I could get it form the repository and recompile nginx.

I’m seeing the same thing happen in Firefox 46.

Just to clarify: this issue also affects Firefox 45. I suppose it’s nginx bug, because we have never experienced it before the update.

This also happens with okhttp 3.2.0 (Android). Last working nginx version is 1.9.13, There I use basic authorization and add an Auth header with a network interceptor with credentials.
