Parse: Could not find the server with the specified host name

Question

Without any changes, I suddenly encountered an inability to find the API URL.

Error: Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found." UserInfo=0x1557a3d0 {NSErrorFailingURLStringKey=https://api.parse.com/2/client_events, _kCFStreamErrorCodeKey=8, NSErrorFailingURLKey=https://api.parse.com/2/client_events, NSLocalizedDescription=A server with the specified hostname could not be found., _kCFStreamErrorDomainKey=12, NSUnderlyingError=0x1556e470 "A server with the specified hostname could not be found."} (Code: 100, Version: 1.4.1)

I saw some old threads about this, but the error was Parse - a DNS problem - and all threads were closed without permission. Any ideas?

thank
