No favicon / No user icon

I have a fresh installation of vaultwarden and I have 2 visual problems:

  1. When I connect I can not see any favicon
    vaultwarden_no-favicon

  2. The icon of the user in the top right corner is empty

I tried several icon services, I changed the value of Icon redirect code, with no luck. The icon-cache directory is still empty, even if the logs show many lines that suggest the request is ok:

[response][INFO] (icon_external) GET /icons//icon.png => 307 Temporary Redirect

Maybe someone has an idea where to look for …

Here is the Support String if it can help:

Thank you for the help !

I made more investigation.
I now have the favicon displayed. The problem was a configuration issue. With ICON_SERVICE: internal it works.

I am still unable to show avatar. The avatar is an SVG definition encoded in base64. Decoded is
<svg xmlns="http://www.w3.org/2000/svg" pointer-events="none" width="48" height="48" style="background-color: rgb(26, 95, 180); width: 48px; height: 48px;"><text text-anchor="middle" y="50%" x="50%" dy="0.35em" pointer-events="auto" fill="white" font-family="&quot;Open Sans&quot;,&quot;Helvetica Neue&quot;,Helvetica,Arial,sans-serif,&quot;Apple Color Emoji&quot;,&quot;Segoe UI Emoji&quot;,&quot;Segoe UI Symbol&quot;" style="font-weight: 300; font-size: 20px;">OL</text></svg>

I tested with Firefox (new profile) and with Chromium and I do not see any colored avatar. I checked the above SVG on SVG Viewer website and it is OK.

Someone has an idea where to look for ?
