DownloadFailedException

On my Raspberry Pi 3 Model B+, with Raspbian Lite, I installed Rhasspy 2.5.0-pre in a docker.
When I change ‘Speech to Text’ to Pocketsphinx, I got the message: ‘Rhasspy needs to download some files for your profile (9 missing, 379.3 MiB)’
When I click on de Downloadbutton, there is the following error:
DownloadFailedException:
(‘https://github.com/synesthesiam/nl_pocketsphinx-cmu/raw/master/g2p.fst/g2p.fst.gz.part-04’,
‘Part size mismatch (got 170747 byte(s), expected 13859764)’)
When I click again then sometimes for other parts of the same file (part-00, part-01, part-02 and part-03).
What is wrong here?
