How I Fixed Alibaba Cloud CDN Image Issues After a Support Showdown
A developer recounts a frustrating exchange with an Alibaba Cloud support engineer over missing images, explains why HTTPS CDN links failed, and shares a step‑by‑step workaround using HTTP links and OSS to restore image accessibility for GitHub‑hosted sites.
In this post the author describes a heated interaction with an Alibaba Cloud support engineer who repeatedly blamed the CDN for images not displaying, despite the author providing clear evidence.
The engineer claimed the request never reached the CDN domain, and later added that the request was a proxy and they could not retrieve the actual CDN response.
The author points out that the image tag contains a data-canonical-src attribute, which originates from Alibaba Cloud's CDN, and that switching the URL from HTTPS to HTTP makes the image load without any other changes.
After the engineer continued to deflect responsibility, the author concluded that the CDN setup on Alibaba Cloud was unreliable for GitHub‑hosted images.
To solve the problem, the author implemented a two‑step workaround:
Replace all HTTPS CDN links with HTTP links, which at least display the images.
If some HTTP links still fail or only partially load, replace those with direct OSS links.
This approach restored image visibility for the author's site that uses GitHub + jsDelivr as a free image hosting solution.
The post also lists three reflective questions about the issue:
Why do you need to redirect the links?
Why can you redirect HTTP CDN links but not HTTPS ones?
If HTTPS works with OSS links but not with CDN, what is the cause?
Overall, the article provides practical insight into troubleshooting CDN image loading problems and highlights the limitations of Alibaba Cloud's CDN in this context.
