ESXi 6.5 with CUC - ova template issue

[Agor85]

Hello,

I would like to provision a CUC machine on ESXi 6.5 U2, but the OVA template (large or 200 users) fails. The issue occurs for CUC 11.5 and 12.5 (maybe 12.0 as well) ova templates.

Vsphere webclient states "unknown error"and the end.

Does anybody hit the same issue?

The cause was the browser after switching to Edge - it worked.
