Webhooks is not working after migration gitlab to new server using backup restore

I have recently migrated my GitLab server from my local server to the AWS EC2 instance. I have used the Gitlab backup and restored in the AWS server. since then after migration of the GitLab server, for all the projects which have already been configured with webhooks in the previous server are getting 500 errors in the new server when we browse the webhooks in that project repository. Can anyone help me in resolving this issue please.
