It probably needs more time to cool beforehand. This report describes how they simulated the cooling process, and the results. They built a physical model of the telescope ("thermal model") just to study that and put it in a cryogenic vacuum chamber.Now begins the process of alignment and calibration of the mirror assembly. THAT is going to take a long time.
"As seen from Figure 6, many of the more massive components, such as the primary mirrors, rapidly cooled at the outset but took up to 32 days from the start of cooldown to begin to exhibit asymptotic behavior to their steady cryogenic temperatures and achieve the 27 mK/hr stability required for optical testing."
