Hello,
I logged in to crestle.ai and found a new design, my credit card stuff was gone and I head to start new. I did so, but now the session url always returns a 404, i waited 20 minutes or so.
What can I do about that?
Just wanted to say that my Crestle.ai sessions are not working today, either. I had successfully launched a session on Friday as part of the fastai class, but that same session now 404s every time I try to restart and launch it.
I’ve emailed support@crestle.ai but have not received a response yet.
I started with paperspace that’s easy to setup as well.
This is happening to me as well 
For what it’s worth, I’ve given up on Crestle and have moved to Salamander. Seems to work great!
I am too facing this issue with them, in last I pushed to clouderizer.com it’s quite stable in comparison with Crestle.
