HPP chain icon not updated on Chainlist (possible CDN caching issue)

[findmytrueself]

Hi,

I’m currently trying to update the HPP network icon on Chainlist, but I’m encountering what appears to be a caching issue.

From reviewing the codebase, it seems that Chainlist fetches chain icons from the DefiLlama icon repository via the following asset URL:
https://icons.llamao.fi/icons/chains/rsz_hpp.jpg

I’ve already updated the icon in the repository through this PR:
https://github.com/DefiLlama/icons/pull/2332/changes#diff-7331405182c395754a97453ae0aa4d970d4f0f07b10f004413d07cd1e92414cc

However, the Chainlist UI is still displaying the old image, which suggests that the asset may be cached (possibly via a CDN).

Could you please advise on the following:

• Is there a cache invalidation process for icons.llamao.fi?
• Would switching the file format (e.g., from .jpg to .png) or renaming the asset be required to force a refresh?
• Alternatively, is there a recommended way to ensure the updated icon propagates to Chainlist?

Thanks in advance for your help.
