Images show "Preview unavailable" for no apparent reason (was working yesterday)

[YG]

Hello,

For some reason several of my pages now display "Preview unavailable" for plain ordinary PNG files. They were showing up on the page as a preview yesterday.

Example:

kevin@Kevin-MacBook-Pro Downloads % file "Tech Diagram - Frontend.drawio (15).png"

PNG image data, 16384 x 13188, 8-bit/color RGBA, non-interlaced

kevin@Kevin-MacBook-Pro Downloads % du -hs "Tech Diagram - Frontend.drawio (15).png"

7.0M - Tech Diagram - Frontend.drawio (15).png

A google chrome extension did this to me.

You can disable your chrome extensions and check again. In my case, "Allow CORS" was the reason.

[external.shanmugavel.eagambaram]

Great. I had image preview problem and it is fixed after removing the above said chrome extension. Thanks

[Devang Patil]

Thanks it works for me.

[Miroslav]

Same issue here. Now it works. Thanks!

[bmendoza]

Thank you! Same issue as well!

[Praveenkumar Masanagi]

Thanks. 

[Roland Kühn]

by me it was quick translate extension 

[Boyd Hong]

2024 now. Any updates? or please let me know where i can upvote this reported issue so Product can start prioritizing the case. 

[Benjamin Acre]

I also have this issue.

we resolved the issue today for our company

[Billy Macrae]

Hi, I can report that we are also experiencing the same issue.

If we could get a fix for this ASAP this would be super helpful. We have a workaround but long term this really needs to be fixed or we may need to look for an alternative.

Thanks,

Billy Macrae

[Fouad]

Never fixed in two years ? I have the same issue.

[Owen Wallis]

Thanks, I'll flag this with the Confluence team

[Kaindl, Benjamin]

and, any outcome?
I still see the issue and the mentioned plugin is not even installed in my chrome.

[dengblom-pcr]

I have the same issue, in a private tab with no extensions enabled, and no VPN running.

[Kristin Clark]

January 2025 this is an issue and has been since January 13th 2025 for us. We can't preview any images but can download them. Please fix atlassian!!! This is such a PITA to download each individual image.

[Gor Kroyan]

+1 to the issue where media files can not be displayed. A bit frustrating because my stories became very boring without media support. If you do not fix this next week, i will start drinking cola and eat Snickers and ruin my help because of the stress. 🤞

[Alex Gardner]

January 2025 still having this issue - I cannot see any images on confluence or Jira?
I have done hard refreshes, emptied cache and reset, restarted laptop, tried different browsers and incognito windows but it is always the same. I can download the image and open it fine but cannot see it in browser

[Chris Wagner]

see my answer below, might help you and we solved it for our company

[David Rahmel]

This problem was driving me nuts. Here is the work around that worked for me. 

The issue for me seems to be with Jira's Create new Ticket dialog overlay. Any time I try to insert images in I get a 'Preview Unavailable'. Doesn't matter if it is from SnagIt or if I try to upload and insert a jpg. If there are Preview unavailable images, the system will not let you submit the ticket so you have to trash them.

However, if I create the ticket text only. I can then go back in and edit it. Then, I can paste images without issue.

Hope this helps someone else.

[Amit Turkenitz]

Brilliant workaround!

[Aaron Appelhans]

I´m facing this issue with integrated sites from our spaces in our organization. Did anyone of Atlassian at least react to this??

[dengblom-pcr]

As of November 2024, this is still an issue for us.

[Praveenkumar Masanagi]

see if it works in safari or firefox

[dengblom-pcr]

We have tried every browser. This has been a constant headache since we were forced to move off of the Server version to the cloud version.

[dengblom-pcr]

Is there an existing ticket for this problem? I can submit one if there isn't

[Megan Danis]

We opened a ticket with the support team ! I'll get back here with an answer asap :)

[josh.sutterfield]

How did it go?

[Ralf Brinkmann]

I am facing the same problem, on my mac with safari, on a windows PC with win 11 (edge and chrome,) on an iPad with safari.
This seems to be a general confluence issue. Why is the support so unbelievable slow?  

[dengblom-pcr]

It's November 2024 and we are still having this issue

[Pierre Lonchampt]

Same here, bug is both on Confluence and Jira :(

[Chris Wagner]

Hi all - we just dealt with the "Preview unavailable" issue for multiple days.  We were given the below information from Atlassian after opening a support case.  However our team determined the root cause was that our enterprise network security tool was selectively blocking the domain that was serving the images.  It was easy to tell this was not an Atlassian-level issue because the images were blocked from our work devices but visible from any personal devices.  We had to add media-cdn.atlassian.com to the list of destinations to specifically be allowed by the network security tool.  That resolved the issue.  No action from Atlassian was needed. 

Hope this helps folks that experience the issue troubleshoot it and find a solution.

Based on our findings and the similar cases we've encountered, could you please contact your internal IT team so they can assist us with this investigation? It would be helpful if they could ensure that our services are allowed through your infrastructure settings.
To assist your IT team further, you might want to share this page with them: IP Addresses and Domains for Atlassian Cloud Products. It contains the domains and IP address ranges that should be allowed through your network/firewall/proxy/VPN settings so our Products can operate properly.

We have the same issue, as also reported here, here and here. We add images to a page, save it, seems to work.

Then edit the page, and the images are shown as “Preview unavailable”.

This happens seemingly at random and is irreversible.

The images are small, mostly pngs of interfaces we are designing. File size can't be the problem.

Very frustrating and leaves Confluence looking amateurish. Aggravated by the fact that already uploaded images can't be added to the page.

Our Confluence service is hosted on atlassian.net.

Are you using Live Editing? 

I've had this problem of images on Confluence pages showing as "Preview unavailable" and have found a solution.

For me, it has been connected with using Live Editing. If I switch the page back to non live editing mode by selecting Publish from the three dots menu, the images reappear. That means I have to go into Edit mode in order to edit the page and then Publish again to see the changes, then refresh in order to see the images, but at least I can see the images!

Live Editing doesn't seem to like images.

[Gabrijel Vetrih]

Hi! It's started happening on our side as well. Some of the images/gifs are not available, and they are shown as "Preview unavailable." Refreshing the site works, and the content does load after that, but I cannot imagine doing it for every single Confluence page I try to access. 

[Deanna Hardy]

We had a user with a weird issue like this out of the blue today.  Control-F5 seemed to work to pull the full page again and then she was fine.  No idea what changed to cause something like that and so far just one user I've heard about.  

[Heike Neumann]

Hello,

I have the same issue with a tiff image. Pdf-file and jpg-image shows preview but tiff-image shows a error message:

Has anyone found a way to display the file?

Thanks an have a nice day
Heike

[Nick Harmer]

I have been able to work around this issue by downloading the images to a local file, then reuploading them through the image macro. This is very painful for pages with multiple images. 

[Sophie Lawson]

Any updates on this?

An incredibly frustrating problem for myself and our clients having to re-save images in JIRA!

[MS]

I have had this issue recently, and I think it seems that on each page where the image previews were broken, there was at least one line with some bold text right before an image. I edited the page and put some plain text after the bold text and before the image, and the image previews displayed again. Maybe I am imagining all of this, but I will keep trying this and report back if it works. :-)

[randy_wang6005]

I experienced the same issue when working with JIRA Software as well, attached image shown as "preview unavailable". However, what I found interesting is the issue only occurs when I tried to attach the image during the issue creation period of time. I can upload the same image without any issue after the issue got created. 

I feel there is some code not rendered properly upon the initial load of the web page. 

[Aaron Appelhans]

@Megan Danis could you please post the ticket key here so that we can vote for the issue?

[erik_unangst]

We are having this issue as well. I'm noticing that it happens when I Copy a Confluence Cloud Page. The images all preview fine on the new Copy of the page, but when I navigate back to the original page that I copied, some of the images on that page now display the "Preview Unavailable".

As an aside, this has also happened to me in Jira Cloud, when cloning a Jira issue by using the Deep Clone App. The newly cloned issue displayed the images fine, but the original that was cloned started showing the "Preview Unavailable" error.
