Glad to hear it seems to be working better! We have done a major rework of the backend layer serving skins, including the cache. If you are able to repeat your test in about a week's time and share your results here in the bug tracker, that would be much appreciated.
Thank you for providing an example, @unknown. We are still working on resolving that issue, which is referenced as WEB-4566 in this bug tracker.
I think we are talking about two different issues that have resulted in some skins being unavailable. This issue, about a sudden disappearance of skins, has been resolved. The other issue, WEB-4566, about skins that come and go due to caching, has not yet been resolved. Rest assured we are working on sorting that out!
This has been resolved. All skins should now be available through http(s)?://textures.minecraft.net/texture/[...] again.
The logo images have been adjusted.
Other issues have had a higher priority, which is why this issue has not yet been resolved. The plan is to have this fixed at latest by 31 December 2022.
Thank you. The certificate has now been updated, as well as the link in the footer of this bug tracker.
Thank you for testing and sharing your results!
