Hi all,

I need your advise about one case :

I have upgraded a vcenter 5.5 to 6.5 U2 VCSA.

Since these steps, I meet strange issues with authentication on Veeam server, backups & replications works & randomly I get this strange error on some halft of jobs :

SOAP connection is not available. Connection ID: [srv.DOMAIN].

Failed to create NFC download stream. NFC path: [nfc://conn:srv.DOMAIN,nfchost:host-10,stg:datastore-11@SRV:srv.vmx].

Soap fault. Detail: '', endpoint: ''

I opened a case with Veeam, they said there is some issues with network, we checheck network everything is Ok.

I think it could be related on psc .

Has someone already identifiy  where the issue could be located ?

I have seen this link about Vcenter limitation http://andyandthevms.com/vcenter-connection-limitation-and-backup-in-big-environments/

As backups jobs are many in same time.

Thanks for your feedback
