Issue while packerizing RHEL8.3 Linux image for Azure Cloud

While trying to packerize a RHEL8.3 LINUX image for Azure Cloud, i am getting below error.

==> azure-arm: Future#WaitForCompletion: context has been cancelled: StatusCode=200 – Original Error: context deadline exceeded

Though the same packer process has been working fine with other images (e.g. RHEL 7.9 Linux) for years now.
