Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH

Solution 1:

This error is definite mismatch between the data that is advertised in the HTTP Headers and the data transferred over the wire.

It could come from the following:

1. Server: If a server has a bug with certain modules that changes the content but don't update the content-length in the header or just doesn't work properly. It was the case for the Node HTTP Proxy at some point (see here)

2. Proxy: Any proxy between you and your server could be modifying the request and not update the content-length header.

As far as I know, I haven't see those problem in IIS but mostly with custom written code.

Let me know if that helps.

Solution 2:

Docker + NGINX

In my situation, the problem was nginx docker container disk space. I had 10GB of logs and when I reduce this amount it works.

Step by step (for rookies/newbies)

1. Enter in your container: docker exec -it <container_id> bash

2. Go to your logs, for example: cd /var/log/nginx.

3. [optional] Show file size: ls -lh for individual file size or du -h for folder size.

4. Empty file(s) with > file_name.

5. It works!.

For advanced developers/sysadmins

Empty your nginx log with > file_name or similar.

Hope it helps

Solution 3:

It could be even caused by your ad blocker.

Try to disable it or adding an exception for the domain from which the images come from.
