Same issue... what's different from the others is that I've been using a Pro Lite account since the start of the year, still have 11TB of available quota and I get this a lot. My IP is the same. Files are 50MB and on occasion larger ones, but the ones JD2's struggling with are these 50MB ones.

I've also tried unticking check reserved traffic and global cdn, same issue.

Edit:
I also noticed the quota doesn't drop a lot. I mean, more than half a year and I've already downloaded about 7 TB, but it dropped 1 TB. Maybe JD2 is still using the free mode even when having an account? IDK.

megous megatools seems to behave the same... it starts downloading with a small speed, then gradually drops to 0, JD2 stops and shows the message, this one keeps downloading with 0KB/s

On Chrome, MEGA's web interface seems to download it properly.

Might it be something regarding what megous said about a change in the API, his tools can't use recently created accounts because MEGA hid the new API, while publicly most tools use the old API and on his end there are a lot of weird issue because of this. IDK, the MEGA web interface with their new API works... everything else doesn't.
