Cannot get my funds


I did not log in my O3 wallet for several months and found out it does not work anymore. I have got .json file. Is there any way to retrieve my funds or they are lost forever?
The message says to resolve host “”: No address associated with hostname.

Kind regards

We rebranded last year, changed the brand image, and launch a new app.
You could download a new O3 wallet via official website , Google Play and Appstore for mobile version. Then you can import your json file, private key, or encrypted key with password.

*the password on the Private key page is a new password you need to create.
