Access of O3 Alternate Calibration Release via GWpy

[Shan909]

Greetings sir,
The same problem has resurfaced:

I have added a detailed post

Is the nds.gwosc.org server down?

I am recieving the same error while fetching AUX channel data for O3a run through the gwpy’s Timeseries fetch function. Error: no data received from nds.gwosc.org for [time segs] I have tried different combinations of time segments, channels, internet providers and even laptops with no success. [1000088628]
