If you look at the address of the webserver that does not have the URL you wanted, it seems to be your email filter company, not the KiCad webserver. It’s the same mail filter company another forum member uses. The advice in that thread was to whitelist the KiCad domain.
I could see that I could access the links from the smartphone using 4G.
Then I realized it could be the Pi-Hole I am using…
Disabling it for some minutes allowed me again to follow the links…
When I click on the button that has this big URL… it shows Google something in the URL, and then after some miliseconds it changes to this one, which is the right one.
Your spam filter modified the link so that It could do a check on the destination before allowing or not the redirect. But that’s a bit poor of your spam filter company not to have a valid URL for the case when the redirect is disallowed. Or maybe your PiHole software isn’t up to date.
As I said: Your spam filter modified the link so that It could do a check on the destination before allowing or not the redirect.
When the redirect is disallowed because of a dodgy destination, then you are directed to this spmailtechno.com domain where presumably the webpage will explain why your destination was banned.
I am using Gmail. This URL is displayed when I hover the mouse over the links there.
I don’t think I actively put something to do that.
This means Gmail is doing that, correct?
However, I am trying to discuss that on Pi-Hole forum, which is exactly like this one. And the links on emails from that Forum are working fine. They send me directly to the post in the forum.
Well I’m only surmising what happens since I don’t run PiHole. One way or another, your request is modified. I know that Gmail also rewirtes URLs in email to subject them to checking so it could be that too. Anyway this is outside the scope of KiCad so I’ll bow out here and leave you to your investigations.
