"failed to log into nfc server" during upload of file to a datastore

[steven_dahlin]

While trying to load a file upto a datastore folder I received the following cryptic error:

Failed to log into nfc server

I am unclear as to what this is since there is only 1 hit for this in the vmware forums (2 hits on google). Nothing really which really answers what this means or how to fix it in my situation. Is it possible that nfc was mispelled and it was supposed to say nfs? Even then I am still unclear how to solve the problem.

Thanks,

Steve

Ran into the same issue, resolved it by adding the ESXi host to DNS.

Probably my fault we only had the IP addres and Hostname in the host file on the vCenter server.

I know this is an old thread, but it comes at the top of a Google search....

For me, my vCenter server wasn't registering right in DNS and I had to add it and it's IP to the HOSTS file on the computer I was connecting the vSphere Client with (in my case, my laptop).

Restarting VC service worked for me as well.

vCenter appliance, see this KB for reference

I know this is a little bit old, but I've experienced the same issue recently.

In my case the problem was related to AUTHENTICATION messed up with VPXUSER.

VPXUSER is created automatically when a host joins a VSPhere environment. By removing the host and adding it again, re-creates the VPXUSER and all went back to normal. It is enough to remove just one host as the VPXUSER is the same for each host on the clusters, so the VPXUSER will be brand new and shared.

That fixed for me.

Try upload to local storage on the host instead. Worked for me.

For me, it turned out to be a FW issue.  I'm not sure which port, probably 902, but once I moved the file I wanted to upload to a server that was on the same subnet, it was able to upload without a problem.

i had this issue too when i connected to the vCenter Server Applicane using the vSphere Client.

I avoid the issue by connecting directly to the ESXi Host using vSphere Client

Thanks for the hint Tim Young‌

Just to say i had this issue when i was connecting directly to the ESXI Server i wanted to put the ISO onto.

Simply resolved it by rebooting the server. Simple but worked.

In my case it was personal firewall, when has been disabled I can access Datastore

Thanks goog hint.

I access the Host directly and I was able to upload the update.

Switching my workstation from Auto to 100 Full Duplex worked for me. I change nothing else, and it worked. Uploading 7.6GB VMDK via webclient.

VMware Version 6.5

Workstation - Windows 7

Firefox 55.0.3

I had this problem recently and was able to work around it by properly reconfigure the DNS server setting of the control station. Unity uses local DNS server to resolve esxi host name

hope this help
