We are trying to validate the following twitter card URL.
We always get an error like this one:
Failed to construct resolution, debugId: 2130052428264-737643
Failed to construct resolution, debugId: 20937788526120-562714
If we validate the url without https, namely http://d.pslot.io/sample, then everything works fine and the card is displayed.
So this seems to be related to HTTPS
