Hi,
I have no idea when this happened but I guess it was after some upgrade, all uploaded images were no longer http but https. I’ve talked to my CDN ISP but they said it was discourse that made the change.
Is that so? How can I keep using http?
Thanks.
Yinglu

Did you tick the “use https” site setting?

Yes, that’s the setting I was referring to.

I haven’t turned on this option. Any other ideas?

What site are you referring to, so that we can see the actual behaviour you’re talking about?

If you dont have a ssl certificate, some browsers refund to display the images, this is my case.

As @Fer_Nando said, both Chrome and Safari refuse to display the images without a valid certificate

The CDN ISP provides a certicificate for you, right?
Which CDN are you using?

Yes, I can request for a free certificate but I didn’t. The CDN is from QiNiu, based in China.

I maked free cert in cloundfront, this solve my problem but other admins of discourse dont have an option for disable https in images when enable the cdn option, this is a small bug.

I don’t know and I doubt Matt can help you here 🙂
Can you confirm:
1. you are running latest?
2. your `DISCOURSE_CDN_URL` is set to: `http://7xibfi.com1.z0.glb.clouddn.com` ? (note how it is http there and not https)

The question is for me?
I have “DISCOURSE\_CDN\_URL: [//cdn.domaincname.com](https://cdn.domaincname.com)” in cdn option, no http or https set here.

Then change it to:
```plaintext
DISCOURSE_CDN_URL: "http://cdn.domaincname.com"
```
Otherwise we will pick HTTPS for you.
