What is the problem you are having with rclone? Upon syncing files from my personal computer to the server, I can no longer open files from the webui because I get "Unfortunately, it appears that the file or some of its data cannot be decrypted." Run the command 'rclone version' and share the full …

Proton is basically hostile towards rclone. Devs of them were here in the forum presenting their concerns and bad ideas. They don't want third party software accessing their storage backend. This company has done good marketing in the past and people think they are somewhat a good company, but th…

[image] Staroy: Proton is basically hostile towards rclone yeah, that is true. for a few years, i was a paid user. this week, they sent to me a renewal notice. i cancelled the account and when they asked why. i wrote 'no support for rclone'

I agree to some extent with both of you, but at the moment it is impossible for me to switch.

Thanks for the excellent report @tigerjack - I've tracked this down and I beleive this is rclone's bug, introduced in the v1.75.0 betas after 2026-07-13 and included in v1.75.0. Sorry about that! First the important bit: your data is safe. The file content is uploaded correctly and rclone can read …

Thanks to you @ncw :slight_smile: I will wait for the fix. In the meantime (and I don't know if useful) my protondrive android app (updated to the 20th of July), differently from the browser, can successfully open such files. As a side quest, would it be possible to check which files were actually …

@tigerjack I've got to the bottom of this - it is an rclone bug in v1.75.0 :frowning: What happened: Proton is migrating Drive to a new generation of encryption and v1.75.0 started uploading new files in the new format, following guidance from Proton on how to do so. It turns out the Proton web app …

Thanks @ncw !!! Well, from what I uderstood, more than an rclone bug, it seems that it is a bug coming from Proton itself, in the sense that they did not update the web app to the newest v6. Am I correct? In this case, once they update their web app, the new files will be readable again, right? If…

@ncw Hey, thanks for being so responsive on this issue! For some reason I still seem to be running into the same "Item cannot be decrypted" problem. Admittedly I am just now setting up my sync with proton for the first time, so perhaps I am doing something wrong. VERSION rclone v1.76.0-beta.10159…
