Issue

Getting error 300 during a dataLoader run.


Cause

Sometimes the vault connection gets closed after 30 minutes. This is due to a vault setting that automatically logs you out after 30 minutes.


Solution

The best solution is to go to your vault configuration located at one of the following paths:

for Vault 2020 and earlier:

“C:\Program Files\Autodesk\ADMS Professional {VERSION}\Server\Web\Services\Web.config” 

for Vault 2021 and newer:

"C:\Program Files\Autodesk\Vault Server {VERSION}\Server\Web\Services\web.config"


Open the file "web.config" with any editor and increase the time for "longCommand"

<timeouts connection="120" defaultCommand="360" longCommand="1800" />

longCommand contains the time in seconds. (1800s = 30min).
