Hi Alireza, As per the log output you have shared, it seems like token renewal is not happening properly due to issue in token retrieval from the response. I have also tried this out and wasn't able to reproduce the issue you are facing with. Anyway this issue might be happen if Refresh token you have used to obtain new token pair is invalid. This might happen if you have modified tokens in deviceConfig.properties file manually or your refresh token got expired.
So one thing you can do is obtain new token pair for your agent and update your deviceConfig.properties file manually with correct tokens. In order to obtain new token pair use following curl command by replacing contents between < and > (Including < and >). curl -k -d "grant_type=password&username=<username>&password=<password>" -H "Authorization: Basic <application-key>" -H "Content-Type: application/x-www-form-urlencoded" https://<IoTS_IP>:8243/token Anyway if you are facing the same issue again and again please provide let us know the steps you have followed. Btw, I haven't noticed your mail for while as you have sent it to my personal email. From here onward, please send any of your WSO2 products related queries to dev@wso2.org and we are happy to help you.
