Keycloak-server connection


I am using keycloak-10.0.2 and every thing is working fine for me except the file upload process.
we are using angular in UI and spring boot service for backend.while upload a pdf file of size 70kb via browser and make a call to java service we do some process on file thats y it takes more time to complete the process in server,before completing the process in server,in UI error is show with empty response and call is getting closed at 2minuts time.

Is there any configuration need to update the time extension i am not sure where the issue is,but without integrating the keycloak its working fine.

Thanks in advance for your help
