问题:

Having some trouble debugging this. I get this error always when i first start my app up, then intermittently thereafter. Could someone please help me by throwing out some debugging techniques? I've tried using a proxy inspector - to no avail, i didn't see anything useful. I've tried the suggestions about setting my SITE_URL in my django settings. I've tried with and without http:// with and without the port... Here's the unhelpful error:

Exception happened during processing of request from ('127.0.0.1', 57917)

ConnectionResetError: [Errno 54] Connection reset by peer

The app seems to function properly even with this connection reset but it's been driving me crazy trying to debug.

回答1:

FFS... so dumb. I noticed that it was always resetting after not finding a favicon so I added one... Even though I never explicitly loaded one, django appears to try and load a default one from the root of the project... This doesn't happen for any of the other devs working on the project either. weird. (For completeness) If anyone else stumbles upon this i used favicon io to make a simple text one. Then i loaded it into my html like so:

{% load static %}
<!DOCTYPE html>
<html lang="en">

<head>
  <link rel="shortcut icon" href="{% static 'images/favicon.ico' %}" />
...

Be sure to set your static path correctly in settings.



回答2:

The same behaviour is seen if the favicon is in .png format as opposed to .ico.

Also, contrary to advice seen on other sites, downgrading Python to v3.6 does not solve the problem. screenshot of error w. png favicon

Seems to be a Django issue, It will probably be fixed permanently in a future Django release.

Following https://bugs.python.org/issue27682#msg348302 I made the changes shown:

I then replaced BrokenPipeError with ConnectionAbortedError. This seems to handle the exception.
