When enabling the QueuedTracking on a site behind cloudflare with HTTP/2+SPDY on (and rocketloader off for piwik) the following error is noticed :

net::ERR_SPDY_PROTOCOL_ERROR

ps. Piwik 2.17.1

Can you try whether this still happens when queued tracking is disabled?

macmenco commented 7 years ago

When queued tracking is disabled it doesn't happen.

Can you maybe see something in the logs on the server or inspect the network in the browser? Feel free to send us a link to your website so we can test it. Our email is hello at piwik.org

Maybe also looking at http://techdows.com/2015/08/fix-chromes-err_spdy_protocol_error.html helps?

I'm able to reproduce this as well, will try and debug it sometime soon!

I confirm this. But it seems to me that it just happens with high-load piwik installations because of cloudflare limiting somehow big request rate to piwik.php on cheap tariffs of cloudflare. Also I've noticed that it also happens with firefox. We've resolved the issue by turning off cloudflare for our piwik installation.
