WSO2 API Manager Synchronization failure on clustering - wso2

Question

I am setting up an API Manager 1.10 cluster, with each component in a separate VM, by following this guide:
https://docs.wso2.com/display/CLUSTER44x/Clustering+API+Manager+1.10.0
But when I start the components, I get the following error:

Also all my css and javascript won't load in the api-store component. I am getting 405 (Get Method not allowed) on all resources.
I am not sure where I am going wrong in both cases.

Answer 1

Setting the DeploymentSynchronization in WSO2_AM_HOME/repository/conf/carbon.xml to false as advised by #Thusitha solved the issue.
The CSS not loading was solved by following this article: https://docs.wso2.com/display/AM1100/Adding+a+Reverse+Proxy+Server
