Android - Retrofit2 - Java.security.cert.certpathvalidatorexception: Trust Anchor For Certification Path Not Found

I want to get data from the server (https://data.egov.kz/api/v2/zheke_zhane_zandy_tulgalardy_k1/v6?pretty) as an array of json objects. But I get this Log: java.security.cert.C

Solution 1:

You server url is https and certificate is already not valid.

Change https to http and it will work.

Else you can install valid SSL certificate on the server.
