Clicking "Publish changes" on es.wp shows ERR_SPDY_PROTOCOL_ERROR
Closed, DuplicatePublic


I click on "Publish changes" (on any Wikimedia project) and changes are not saved.
Steps to reproduce:

  1. Open:
  2. Click on: "Editar código" (Edit code)
  3. Click on: "Publicar cambios" (Publish changes)
  4. Changes won't be saved and a DNS message (ERR_SPDY_PROTOCOL_ERROR) error appears.

Expected result: Clicking "Publish changes" (on any Wikimedia project), changes should be saved and no error message should appear.
Actual result: Clicking "Publish changes" (on any Wikimedia project), changes won't be saved and ERR_SPDY_PROTOCOL_ERROR appears.

Hi @Agusbou2015, thanks for taking the time to report this!
Unfortunately this report lacks some information. If you have time and can still reproduce the problem: Please add a more complete description to this report.
That can be a clear list of specific steps to reproduce the situation, as little details sometimes matter, so that nobody needs to guess how you performed each step, describing actual results and expected results after performing the steps to reproduce, providing a link to a public website where the issue can be seen, etc.
You can edit the task description by clicking Edit Task.
Ideally, exact and clear steps to reproduce should allow any other person to follow these steps (without having to interpret those steps) and see the same results. Problems that others can reliably reproduce can get fixed faster. Thanks!

I have added more details and steps to reproduce the bug.

Quoting @Tgr from T108449#1839934:

ERR_SPDY_PROTOCOL_ERROR is a very generic error message that basically means something went wrong with the communication with the web server while using SPDY o HTTP/2. That could be a browser bug, an Apache or Varnish bug, a web server configuration problem, whatever.

If the error still occurs and you can reproduce it with some reliability, I think the way forward is to log the network details as described here and file a bug with those details attached against the Chromium project; they can at least figure out what the exact protocol problem is.

Quoting @CDanis from T213214#4870225:

If you can manage to reproduce this consistently, even for a few minutes, capturing a Chrome NetLog using chrome://net-export would probably shed light on what is happening.
Details on what is captured and how to use it are at
