We are using Nexus 3. From bitbucket cloud, we are trying to connect to nexus repository hosted on-prem through webSEAL URL accessible from internet.
We are unable to login to nexus when accessing it through webSEAL with 403 error and receiving this error Access to XMLHttpRequest at ‘https://Onpremnexus.com/service/rapture/session’ from origin ‘https://webseal/nexus’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
The above doesn’t log in request.log file.
While accessing internally, we have no issues with login.
Workflow from internet:
Application/user-> webSEAL → Apache 2 Proxy → Backend nexus application
Application/user → Apache 2 Proxy → Backend nexus application
Kindly help me in resolving the issue.
Thanks in advance!!
