When the error message "Network unavailable" occurs, please check if you are in any of the following situations.

  1. Please check your phone settings. Check if you have banned “eWeLink” to use WiFi/4G. If you have disabled the network for eWeLink, please enable it.
  2. If you can use the App on your phone normally in 4G network, but when switch to WiF, it continuously prompts “Network Unavailable”, this problem is caused by unstable WiFi network.
  3. If you only get “Network Unavailable” error in eWeLink app, please contact the telecommunication carrier and check why you cannot parse these two domain names: cn-long.coolkit.cc and api.coolkit.cc. Ask for their help to parse the two domain names.
