Certreq -submit run locally returns successful but run remote via invoke-command hangs

Question

Good morning I have been struggling with a certificate request script.
The requesting server is in the dmz and I have a management server internally.
I successfully create the Inf file, as well as the req file then copy the req file to my internal management server. Once copied internal I attempt to run the following command from my laptop executing as my admin account
$Fqdn = "server.dmz.com"
$managementServer = "InternalServer"
$Path = "C$\Test\CertRequests"
Invoke-Command -ComputerName $Managementserver -ScriptBlock {param($CertificateAuthority,$FQDN,$Managementserver,$Path) certreq.exe -submit -attrib "CertificateTemplate:DVNOfflineComputer" -config "$CertificateAuthority" "\\$Managementserver\$Path\$FQDN.req" "\\$Managementserver\$Path\$FQDN.crt"} -ArgumentList $CertificateAuthority,$FQDN,$Managementserver,$Path
This exact command pasted into a powershell window locally on the management server returns the crt file.
Run via invoke-command just hangs forever. I even tried to the Silent=True in inf file as well as -q but neither worked.
Any help is greatly appreciated.

Hi Jason,
I reform the script as below, and add the "test-path" to check if the .req and .crt files exist, please also note you haven't assign value to the "$CertificateAuthority" variable:
$Fqdn = "server.dmz.com"
$managementServer = "InternalServer"
$Path = "C$\Test\CertRequests"
$CertificateAuthority = "something"
$script={
param($CertificateAuthority,$FQDN,$Managementserver,$Path)
test-path "\\$Managementserver\$Path\$FQDN.req"
test-path "\\$Managementserver\$Path\$FQDN.crt"
certreq.exe -submit -attrib "CertificateTemplate:DVNOfflineComputer" -config $CertificateAuthority "\\$Managementserver\$Path\$FQDN.req" "\\$Managementserver\$Path\$FQDN.crt"
Invoke-Command -ComputerName $Managementserver -ScriptBlock $script -ArgumentList $CertificateAuthority,$FQDN,$Managementserver,$Path
If there is anything else regarding this issue, please feel free to post back.
