You downloading it from zapstore?

Hostname errors are usually DNS issues, if you have a device like a Samsung or xiaomi or any device with mediatek chipsets I see a lot of this happening in random apps and usually rebooting fixes it

How are you login to the web apps? Just scanning the qr code from coracle on the desktop for example?

I'll do more tests with my device and I'll try to see if I have some other device that's not a pixel to see if I can reproduce the issue
