Garry's mod workshop addons download freeze

My workshop addon downloads freeze with this console message:

Transferred 56.0 MB (58720256) in 10 seconds (I got the download to 45% and it didn't download this round)
Transferred 0 B (0) in 10 seconds
Dopwnload Finished
Error downloading file - Timed Out
END: DownloadAddons

how do i download my addons?
or, where is the cache? (as even if i remove garry’s mod completely it still resumes from the last point)

EDIT: and with an 100/100 connection i don’t think it really times out
