Hi, I have setup an OpenGTS instance on CentOS 7 with CellTrac with the below versions. CentOS 7: 3.10.0-1160.el7.x86_64 OpenGTS: 2.6.7 Java: 1.8.0 Apache Tomcat: 7.0.109 ctrac: 2.5.8 MariaDB: 5.5.68-1.el7.x86_64 I have mostly followed the official installations guides OpenGTS and CellTrac. I have opened the required ports on the firewall and created the systemd service unit files. The services start up. The problem is that I have errors in /usr/local/tomcat/logs/localhost.2021-05-04.log and /usr/local/tomcat/logs/localhost_access_log.2021-05-04.txt,...
