Hey at the moment I use the caddy web server as reverse proxy in front of the dotnet core umbraco application. Now I saw that images and other files get loaded over http. Can someone tell me how do I have to confiure umbraco to solve this problem? My website is https://danobe.dev and when you look at the canonical url it uses http:// instead of https. I use the SEO Toolkit and thought it is regarding to this plugin the problem. But now I figured it's because my dotnet core application runs on http. Has someone any hints on how to solve this issue? Kind regards, Daniel

What code are you using to generate the canonical?

I use SEO Toolkit which autogenerates it. tag is used ... I testet also on the images the following @Model.KindOfEquipmentPhoto.Url(mode:UrlMode.Absolute) which gives me a http:// address ... so the whole application must run in http context but caddy offers https ...

While I haven't tested it with Umbraco it should be possible to use the Forwarded Header Middleware (see. https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/proxy-load-balancer?view=aspnetcore-7.0) to override the protocol using the

X-Forwarded-Proto

header, which IIRC Caddy sets by default. Just make sure it's registered before any Umbraco middleware.

You could always do what I've done a few times which is:

Copy code

<link rel="canonical" href="https://danobe.dev@(Model.Url())">

It's a bit of a cheat but it works 🙂

yeah but i've also open graph image tags wich run also at http:// at the moment, so its no fix for me ... i've implemented now the fix from @rasmusjp but haven't deployed it yet because I have to do a few fixes before deploying .. I let you people know if it worked! 🙂

@rasmusjp I deployed my site today and had to grind a little bit. Turns out this line solves the problem:

Copy code

csharp
app.Use((context, next) =>
{
    context.Request.Scheme = "https";
    return next(context);
});

Thank you for your help! 🙂
