> [@bjkroege13](#): > > Maximum execution time of 30 Maximum execution time of 30 seems to be the issue here. If you’re managing the server you need to increase this. This has more to do with your WebServer setup than it with Mautic. The insertion of the data in the Database takes more than 30 Seconds in this case. The server only allows it to run for 30 Seconds before killing the action which leads to your error.
