I have this error in release when I return to web page after one day.
B4X:
HTTP ERROR 500 java.lang.RuntimeException: com.mysql.cj.jdbc.exceptions.CommunicationsException: The last packet successfully received from the server was 92 914 945 milliseconds ago. The last packet sent successfully to the server was 92 914 945 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.
