          if (this.isOnline()) {

            data = Object.assign(data, {rnd: new Date().getTime()});

            if (this.debug_mode) {
              console.log("datadata", data);
            }

            let params = " params: ";
            for (let field in data) {
              if (field == "p") {
                params += " p:*****"
              }
              else
                params += " " + field + ":" + data[field];
            }

            if (this.debug_mode) {
              console.log('data_params', data);
              console.log("params", params);
            }

            this.logProvider.writeLog("RETRIEVE: start post on link " + link + " " + params);

            this.http.sendRequest(link,
                {
                  method: 'post',
                  data: data,
                  timeout: 30000
                }
            ).then(result => {

              // prints 200
              console.log(result.status);

              try {
                result.data = JSON.parse(result.data);
                // prints test
                console.log(result.data.message);

              this.logProvider.writeLog("RETRIEVE: finish post on link " + link);

              if (this.debug_mode) {
                console.log("result.data", result.data);
              }

              //console.log("result", result);
              resolve(result.data);

              // prints 200
              console.log(result.status);
            }).catch(err => {

              // A client-side or network error occurred. Handle it accordingly.

              if (this.debug_mode) {
                console.log('An error occurred post:', err);

I also have same error I already create www/certificates and put the key file DER in there but I got this error after run. currently I use "cordova": "^10.0.0" and "cordova-plugin-advanced-http": "3.0.0". My project is cordova monaca. Anyone have solution for this? Thank you so much.

I already solved this problem because I mistaken convert file to .der instead .cer files. Thank you so much.

I also encountered the same error. My certificate was generated by openssl. What tool was used to generate your certificate?
