HTTPS API Troubleshooting
  • All HTTPS API are case-sensitive. Request path and query parameters letter-case shouldn't be changed.
  • Make sure you're using the correct server. Blynk currently have 2 clouds running.
    The old cloud (no longer supported) with host blynk-cloud.com and the new cloud with host blynk.cloud
  • In case you're getting the Invalid token. response from the HTTPS API,
    and you're sure the device auth token is correct - it could be a GEO DNS issue.
Due to current GeoDNS settings you need to put server address with suffix manually depending on your region: https://fra1.blynk.cloud/ – Frankfurt https://lon1.blynk.cloud/ – London https://ny3.blynk.cloud/ – New York https://sgp1.blynk.cloud/ – Singapore https://blr1.blynk.cloud/ – Bangalore
The server region could be found in the right bottom corner of the web interface.
