Jelastic maven plugin throws gateway time-out on deploy goal - maven

Question

I'm using jelastic to build and deploy spring-boot application with a many classes. It takes few minutes for jelastic to redeploy this application. But when environment starts reloading after plugin execution - plugin throws Gateway time-out.
Here is plugin configuration:
<plugin>
<groupId>com.jelastic</groupId>
<artifactId>jelastic-maven-plugin</artifactId>
<version>${jelastic-maven-plugin.version}</version>
<executions>
<execution>
<phase>install</phase>
<goals>
<goal>deploy</goal>
</goals>
</execution>
</executions>
<configuration>
<email>${jelastic-maven-plugin.login}</email>
<password>${jelastic-maven-plugin.password}</password>
<context>${jelastic-maven-plugin.context}</context>
<environment>${jelastic-maven-plugin.environment-name}</environment>
<comment />
<api_hoster>${jelastic-maven-plugin.hoster-api}</api_hoster>
</configuration>
</plugin>
Here is log from console (I removed File URL from this trace, but I've checked - it was valid):

I checked in console that environment was reloaded as the result of this execution.
How can I increase time-out in jelastic maven plugin?
