Hi Alireza, This could be happening due to not having correct certificates related to your virtual private server.
Please follow these steps to get rid of the issue. 1. Run the IoT_Home/scripts/change-ip.sh scripts file to change the configurations and IP/hostname of the server. (Make sure to give either IP of the server or the hostname if you have configured a one) 2. If your VPS has a machine name please add it into the /etc/hosts file as follows 127.0.0.1 machine-name if above does not solve the issue enable the debug logs send us the log files. Please follow these steps to enable debug logs. Go to the IOT_HOME/conf/log4j.properties file. Uncomment the following #log4j.logger.org.apache.synapse.transport.http.wire=DEBUG #log4j.logger.feign=DEBUG Comment the following log4j.category.org.apache.synapse=WARN Then restart the IoT server and try to login to the devicemgt application. After the error happens, please send IoT_HOME/repository/logs/wso2carbon.log file.
