Looks like a duplicate of #33.
I never had that issue, difficult to debug without being able to reproduce.

I'm able to download all-day 8h rides with GPS and all (800KB route) from my own V2 (... unless that watch crashes during recording, already happened a couple of times...).

Take a look at the SYSLOG.TXT log file from the watch, might be an internal condition.

Same problem. Watch is polar ignite and platform windows 10. Sync freezes instantly when downloading journal and GET freezes on some bigger files.
[update 17/9] i tried this software on other laptop that has linux (pop_os) on it and polar_ftp worked with zero problems.
