ESPHome new node creation : connection error

Sorry for putting this question. As i have already found many threads on this topic but could not solve it. Completely new to HA.

Newly installed Hassio in Raspberry pi 3B+ board, installed ESPHome as per the guide. Tried to compile the new node created but getting connection error for

[API] ConnectionError: HTTPConnectionPool(host=‘’, port=80): Max retries exceeded with url: /v2/lib/search?query=name%3A%22ESPAsyncTCP-esphome%22 (Caused by NewConnectionError(’<urllib3.connection.HTTPConnection object at 0x75b91f90>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution’,)) (incremented retry: max=5, total=1)
APIRequestError: [API] Could not connect to PlatformIO API Service. Please try later.
"Could not connect to PlatformIO API Service. "

Please help me to guide where it went wrong or any other settings required for this.

Likely platformio is having errors again. Wait a while, its the internet.

Thanks for the reply… i am trying from last 3 days. Hope it will up again soon. Let me keep trying.
