TotalSegmentator License Activation Issues

I have completed the replacement, but it still failed. Could you please help me figure out what the reason might be?

Failed to set TotalSegmentator license.

Command ‘[‘C:/Users/localadmin/AppData/Local/slicer.org/Slicer 5.8.1/bin/../bin\\PythonSlicer.EXE’, ‘C:\\Users\\localadmin\\AppData\\Local\\slicer.org\\Slicer 5.8.1\\lib\\Python\\Scripts\\totalseg_set_license.exe’, ‘-l’, ‘aca_L3S919KUQIFOHA’]’ returned non-zero exit status 1.

Could you kindly confirm whether the connection failure is network-related?

When I run the license tool from the command line:“C:\Users\localadmin\AppData\Local\slicer.org\Slicer 5.8.1\bin\PythonSlicer.EXE”
“C:\Users\localadmin\AppData\Local\slicer.org\Slicer 5.8.1\lib\Python\Scripts\totalseg_set_license.exe” -l aca_L3S919KUQIFOHA

t times out while attempting to reach backend.totalsegmentator.com:80.

My security team is willing to open outbound access.
Should I allow TCP 443 (HTTPS) to https://backend.totalsegmentator.com/ for the validation to succeed?
