Pagespeed causing broken CSS file

[Jason Carlton]

I have a CSS file at:

/includes/css/styles.css

It usually works fine, but yesterday it started breaking. I see that pagespeed is modifying the link to:

/includes/css/A.styles.css,qh=1616175274.pagespeed.cf.XpobYhYkgY.css

And the error log says:

[mod_pagespeed 1.13.35.2-0 @4190] A.styles.css,qh=1616175274:0: Resource based on https://www.example.com/includes/css/styles.css?h=1616175274 but cannot access the original

I can use ModPagespeedDisallow to disallow the directory, and then it's not broken anymore. But then, of course, I lose the advantage of pagespeed!

Any other suggestions on how to make it work, or to trace down why it stopped working in the first place?

Messages says pagespeed can't found the original file....

And I see the resource is fetched via http request.

How have you configured https fetch?

Is the https version of the site authorized?

[Jason Carlton]

What do you mean by "authorized"?

I don't have any specific configuration regarding HTTPS, but I understand that FetchHttps is on by default:

https://www.modpagespeed.com/doc/https_support

If I manually go to https://www.example.com/includes/css/styles.css?h=1616175274 in the browser then it loads just fine, but of course https://www.example.com/includes/css/A.styles.css,qh=1616175274.pagespeed.cf.XpobYhYkgY.css is 404.

Is enable, but need some additional config, like:

# Certificate Authorities directory, not your domain SSL keys

ModPagespeedSslCertDirectory directory

# Web Server's HTTPS client SSL key, not your domain SSL keys

ModPagespeedSslCertFile file

This last is not needed if the linux distro is Debian/Ubuntu.

Think pagespeed fetch is like a browser, to navigate to a https site, you need the CA certificates.
