The variable '$defaultNSXConnection' cannot be retrieved because it has not been set

[dcvlehr]

When attempting to connect to the NSX manager, I get this error.

The variable '$defaultNSXConnection' cannot be retrieved because it has not been set. At C:\Program Files\WindowsPowerShell\Modules\PowerNSX\3.0.1174\PowerNSX.psm1:25305 char:41

• [PSCustomObject]$Connection=$defaultNSXConnection

What command do you are using ?

[dcvlehr]

Connect-NsxServer -vCenterServer ServerName.com

I've tried by IP address as well. Docs said -vCenterServer was prefered. I also have the powercli module installed, and the connect-NsxServer cmdlet will also try to use an existing vSphere connection and automatically attempts to hit the correct NSX manager IP without ever referencing it

Strange what release of PowerShell ? do you have try a older release ?

Now I'm getting this error after closing my powershell ISE and reopening and trying again. Strange, because I connect to Vsphere just fine and get run Get-VM.

None of this makes sense because i can do postman API calls with my same credentials to this nsx manager and return things.

What NSX Release ?

you try to connect directly to NSX Manager ?

I've tried Connect-NsxServer -NsxServer 10.X.X.X -Credential $cred

[dcvlehr]

I am now able, without PowerNSX at all, to connect to my NSX manager via pure powershell invoke-restmethod

#logon credentials
$username = 'me'
$password = Get-Content "C:\Users\myuser\Desktop\vcenterpassword.txt" | ConvertTo-SecureString
$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $username, $password

#format credentials
$auth = [System.Convert]::ToBase64String([System.Text.ASCIIEncoding]::ASCII.GetBytes($Credential.UserName+':'+$Credential.GetNetworkCredential().Password))
$head = @{'Authorization' = "Basic $auth"}

#API URI to conenct to
$URI = "https://10.x.x.x/api/2.0/services/securitytags/tag/securitytag-13"

#send API call
$request = Invoke-RestMethod -Uri $URI -Method Get -Headers $head
$request

This returns a security tag just as it did when using Postman. Still have no idea why powerNSX doesn't work. Was really hoping to abstract some of this.

i ask the NSX Manager release

[alagoutte]

and for your issue about SSL/TLS it is coming from need to disable certificate check (it is set automatically when launch connect-nsx...)

[dcvlehr]

NSX Manager Version: | 6.4.5 Build 13282012

I can get around the TLS issue easy enough. Just wish I could actually use powernsx >.<

[alagoutte]

You are using the vCenter name when connect ? (and the administrator@vsphere.local) account ? (not the NSX Manager)

[dcvlehr]

So that worked with those credentials...how am I able to make any API call I want outside of powernsx with my admin credentials, but using powernsx requires this specific account?

[alagoutte]

you can the use admin account of NSX Manager ? or a another account on vSphere ?

[dcvlehr]

I have been making API calls to NSX directly with my personal admin account. I was finally able to do it with the power nsx module using the adminstrator@vsphere.local
