: Why is Chrome not allowing resources to load? I have a web server, built into a device, sitting behind a firewall. The web server is on port 80, but many times port 80 is already in use

@Frith620

I am seeing this on Chrome 63 where there is a bad proxy.
To resolve:


Open chrome://net-internals/#proxy
Click Clear bad proxies


The chrome://net-internals/#events tab can be useful to view what is going on.

Chrome 55 was notorious for net::ERR_INVALID_HTTP_RESPONSE, when using custom ports outside of 80, 8080 and 443. This affected thousands of servers but notably Shoutcast Version 1 and 2.

A simple fix may just be to use 8080 instead of 9300 as it can coexist with 80. But your issue here is your browser, not your server or hardware. The real fix is to update your browser to a version that is considered stable and up to date.

Google released a build that fixed this very issue after many complaints. Considering that we are now in version 59 stable and 60 stable development, you should update your Chrome to resolve this issue, after all that's why we get new versions of browsers all the time to fix issues, sometimes new fixes break things etc.

Your server is not serving CSS or JS correctly, and possibly other server-side resources. This is actually reported in the Firefox console.

Doing a curl on a element or page should look something like this:


www.bybe.net/wp-content/themes/showboat/style.css

Doing a CURL on your resources returns this:



NULL
NULL



The code above is not valid and should not work at all. The reason that FireFox is working while Chrome is not is because Chrome is more strict when it comes to security concerns.

Doing a CURL on your pages returns:


HTTP/1.0 200 OKAY
Content-Type: text/html
Cache-Control: no-cache



To replicate this issue, you can do a online test yourself using online CURL. To add your username and password, click + Add Option, find user -u and click it, then Insert Attributes as YourUsername:YourPassword.

So, the solution to all your problems is to fix your web server serving all files and pages correctly.
