I think the default max upload size is ~21mb…
You’ll have to modify the web.xml file and restart the gateway to increase it. In $IGNITION/webserver/webapps/main/WEB-INF/web.xml
there’s a section like this:
<servlet>
<servlet-name>DataRoutes</servlet-name>
<servlet-class>com.inductiveautomation.ignition.gateway.dataroutes.DataServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<multipart-config>
<max-file-size>20848820</max-file-size>
<max-request-size>418018841</max-request-size>
<file-size-threshold>1048576</file-size-threshold>
</multipart-config>
</servlet>
You can change the max-file-size
entry to something higher.
