Deployment of war file to Tomacat using application management

Build the war but not able to upload to Tomcat server hosted in linux server in cloud. After 2% uploaded 403 Access Denied error is getting. I could upload other spring war files but not built using CUBA

If I would be on your place, I would check cloud server logs for possible error messages. Then asked their support about this problem.
Maybe there is a file size limit?

Thanks Alex. I uploaded directly to the server instead of managment console. and its working.
