We have released new version of qualys-cs-plugin as 1.6.2.6

After releasing the qualys-cs-plugin, respective files are updated in jenkins repo at https://repo.jenkins-ci.org/releases/com/qualys/plugins/qualys-cs/1.6.2.6/ (PFB)

When we sync our Jenkins instances update center, we can see the new release is reflected in updates as well.

However, this newly released version is not reflected https://plugins.jenkins.io/qualys-cs/#releases even after a day of files being uploaded successfully to Jenkins Repo.

We need help here to understand -

1. What is the root cause of this issue?
2. How it can be resolved? 
3. What should be next course of action from our end towards fixing this issue?
