Die NASA repariert den Heliumfluss in der oberen Stufe, die Vorbereitungen für den Rollout werden fortgesetzt – NASA

> Engineers determined a seal in the quick disconnect, through which helium flows from the ground systems to the rocket, was obstructing the pathway. The team removed the quick disconnect, reassembled the system, and began validating the repairs to the upper stage by running a reduced flow rate of helium through the mechanism to ensure the issue was resolved. Engineers are assessing what allowed the seal to become dislodged to prevent the issue from recurring.

This means it wasn’t a stage side issue, but ground side interface issue. Different from last time when it was stage side issue.
