Are you able to check if this works on Windows for you?
I just checked and experienced the same issue in Windows.
Does using a full browser work on both platforms?
Yes that does work on both platforms (took me a while to test on Windows).
Issue still present in current version of Steam. Any update on this?
To be clear, I noticed in big picture mode the browser was not getting the payment session data, which is part of the URI.
I recall I was able to pay with the desktop client, but not with the big picture client.
I can try desktop again, but desktop mode is a few reboots away... :-(.
To work around it I just put money on the account using a normal browser.
Ohhh wait... I have a totally different failure... I get a 404 due to the third party payment processor not getting the session data... Not an unable to connect to server...
Ok, sorry my bad: I have a different bank (rabobank) that probably has different requirements, maybe the triodos bank uses websockets.
On ideal payment the actual payment is done after a redirect to the users own ideal bank portal.
I will file a bug for the big picture session data issue, but I thought I saw something related that it might have been fixed.
This bug however is after the initial ideal portal, going to the portal of the bank itself. I will try a payment using my bank.
Ok, I've tried steam client ideal payment using the rabobank, and the rabobank backend works.
The difference with TS is that I select ideal, then I select rabobank, then I select proceed. Then a popup appears.
In his case it seems that just selecting triodos bank is all it needs. That should be sniffable.
To be clear: in respect with #5078, I had to "hack" my steam machine to get the desktop client. Heh... just put an exec of a decent wm in the .xessionrc, like icewm.
As a fellow Triodos customer, I can confirm this issue under Debian buster.
Nothing extracted yet.
