Nginx PageSpeed SSL Added Cloudflare, now getting 403 on pagespeed admin

What would best troubleshooting steps be after enabling cloudflare, and now cannot access pagespeed admin? I've confirmed pagespeed handler and custom config is properly set, as well as vhost. (no changes made to these settings after enabling cloudflare...) Is there a guide for enabling cloudflare with pagespeed already installed?

No, I did not.... and I did not see that in my vhost's conf file... but I added it, based on this post after searching this forum:
Wordpress - Plugin not working all of the time - takes long time to load

But when I subsequently run nginx -t, I get the following:

Code:

nginx: [emerg] SSL_CTX_load_verify_locations("/usr/local/nginx/conf/ssl/cloudflare/[mydomain].com/origin.crt") failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/usr/local/nginx/conf/ssl/cloudflare/[mydomain].com/origin.crt','r') error:2006D080:BIO routines:BIO_new_file:no such file error:0B084002:x509 certificate routines:X509_load_cert_crl_file:system lib)
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed

yep, that is properly configured.

 

update: I was updating the ssl conf; now that I'm using cloudflare I switched back to the non-ssl conf.

 

I have now disabled pagespeed and I may go pro with cloudflare. But first:

In these instructions:

I'm getting a 404 not found when trying wget -- https://support.cloudflare.com/hc/en-us/article_attachments/201243967/origin-pull-ca.pem. Turns out, that URL seems to be inaccessible from my browser as well?

 

found it here: https://support.cloudflare.com/hc/en-us/article_attachments/360044928032/origin-pull-ca.pem

@eva2000, I think you will want to update the instructions, the URL has changed.
