Yesterday we had a server issue due to our infrastructure upgrade. We didn't test the new server well enough. Our apologies for this.
It should be all good now.
On the bright side, Cameyo's infrastructure is now upgraded and more powerful.
I am having this problem too. I tried both the Public apps and uploading my own and using both Chrome and Firefox, either way I get this connection error. I did try the android app, which seems to work.
