Why such an error when sending a webhook?

Question

Bots

I created a bot, registered all the fields for the viber, received a token, inserted the token into a file
I send a web hook
and I get this error

{"status":1,"status_message":"Result[HttpRequest[POST /index.php HTTP/1.1]@2b0700c5 > HttpResponse[null 0 null]@5c498248] java.net.UnknownHostException: viber.wd-king.com .ua: Name or service not known","chat_hostname":"SN-CHAT-10_"}1

I followed this instructions

Answer 1

At the time of the request, Viber was unable to resolve the name viber.wd-king.com.ua. Wait a while for the DNS to clear up.
