Can't build ios on Windows and Ubuntu

Hello,

Last month, I created the expo project with 3.11.7
At that time, I build the ios on my windows 10.

But this month, I created the expo project iwth 3.15.5
Now can’t build the ios on my windows and Ubuntu server.
It shows 502 Bad Gateway error.

I can login on the browser, but can’t login on command line.
What’s the problem?

Kind Regards
