Problem with displaying favicons of embedded websites

[ubodigat]

Hello everyone,

I don't know if it's me or a general problem. I added the Adobe website (https://www.adobe.com/home) to an entry. Unfortunately, the website's favicon isn't displayed, but only the default icon for the entry. All other websites I have added work fine, except for Adobe.
What could be causing this, or how can I fix it?

Best regards

If I try to load an icon via /icons/adobe.com/icon.png or /icons/www.adobe.com/icon.png I get the following error.

[2025-10-15 10:43:51.820][vaultwarden::api::icons][WARN] Unable to download icon: Req.
[CAUSE] reqwest::Error {
    kind: Builder,
    url: "data:,",
    source: BadScheme,
}

So I'd guess this is a general problem. Looking further into it, it seems like this also does not work on Bitwarden because instead of an icon I get a page that just say Internal Server Error.

As a temporary fix you could remove the www.adobe.com.png.miss file from the icon_cache folder and use a custom icon instead as described in the wiki.

All right, thank you @stefan0xC for the answer and your time. (;
I'll do it with the custom icon then

Sorry guys, I don't understand how you fixed it. I resolved with many websites with subdomains, but that's not this case. Where is the icon cache folder? And the guide doesn't really explain how to use custom icons, can you help me? Thanks in advance!

[stefan0xC]

the icon cache folder is in your data folder. what exactly is unclear? if you place an icon where the web vault expects one (and make sure it stays recent) it will be used instead as long as there is no miss file

I apologize, I was searching for a bitwarden solution... I thought this thread was about it not vaultwarden😅 anyway thank you!
