Airgapped license issues

Hello all,
After failing with unexpected behaviors, with Engineers decided to switch to Airgapped.
Infra Provisioning completed, however when uploading license yaml I got error:

Error description
Encountered an error while uploading license: Failed to fetch
Run this command to remove the app…

Did not yet deeply looked into logs though…

this looks suspicious:
kubectl logs kurl-proxy-kotsadm-76fb65b66c-9z6p9 -f
http: TLS handshake error from remote error: tls: unknown certificate

Hello Robert,
I beleive you don’t have the right license file. Could you send me your license file by email I’ll send you right format if this is the issue.
Also what was the last bug that you encountered on the other installation?
