Not sure to fully understand your issue. Your card is not accepted by https://donate.yunohost.org/ ?
If it is the case you have a contact link at the bottom of the page to reach people that can help you solve issue with donation to the project.
I came over “yunohost . org / index.de.html” to “yunohost . org / donate.de.html”
There I startet the donation via ““checkout . stripe . com / c / pay” .
Finally my bank rejected the request.
Was that phishing? Should I use instead “your” link?
Your link is also valid. Both redirect to stripe which handle the payment part.
If it’s a problem between your bank and stripe, I know that paypal donation are also available via liberapay. See https://de.liberapay.com/YunoHost/donate
Used your link successfully! Done.
Thanks for your help. (No idea, why the other version failed…)
