What is the problem you are having with rclone?

About one month ago, i can connect from my Manjaro desktop with my transip / stackstorage cloud with rclone.
From my Ubuntu server 22.04 i still can connect to this cloud with rclone. But with the newer version of rclone on my desktop i got this error:
Failed to create file system for "transip:": the remote url looks incorrect. Note that nextcloud chunked uploads require you to use the /dav/files/USER endpoint instead of /webdav. Please check 'rclone config show remotename' to verify that the url field ends in /dav/files/USERNAME

When i test the url direct in browser (https://mydomain.stack.storage/remote.php/webdav) i get an OK.
And also for: https://mydomain.stack.storage/remote.php/dav/files/technout i get an OK.
Username and password are not changed en no config file was changed by me. But after this i did some testing, delete the transip entrance and added it again, but no luck, same error.

I hope i've given enough information to be helpful, and thanks for maintaining this cool project!

I removed version 1.63.1 and installed rclone-1.59.2-1
Now it just works.

[ncw]

Can you try the latest beta please? Its possible we've fixed this already.

[technout]

I tried it today with the latest beta, but the error is the same:
sudo rclone lsd transip:/ -vv

[ncw]

@devnoname120 do you have any ideas? Can the url be transformed?

[technout]

To be more clear: it is a bug report, not a question.

The error message

Failed to create file system for "transip:": the remote url looks incorrect. Note that nextcloud chunked uploads require you to use the /dav/files/USER endpoint instead of /webdav. Please check 'rclone config show remotename' to verify that the url field ends in /dav/files/USERNAME

Is telling you to change your URL from https://mydomain.stack.storage/remote.php/webdav to https://mydomain.stack.storage/remote.php/dav/files/USERNAME where USERNAME is your username.

Can you try this?

[technout]

Yes, i've tried this, this gives the same results.

[devnoname120]

@ncw I'm not entirely sure whether it's safe to automatically fix URLs from /webdav to /dav/files/USERNAME. This error message was added before I took over the NextCloud chunked uploads feature and I didn't invest the time to find out if it's legitimate or not. It's unlikely that I will be able to look into it in the coming 3 weeks.

[ncw]

@technout

Yes, i've tried this, this gives the same results.

Can you show the log with -vv for this please because I think this if it is going to fail, it should at least fail in a different way!

[devnoname120]

@technout Also, why did you configure the remote as a NextCloud remote? Transip STACK is based on ownCloud, not NextCloud. Chunked uploads for ownCloud are not supported by rclone.

[technout]

Yes, you're right! I thought it was NextCloud but configuring it as OwnCloud fixed the problem! All these years it did work with NextCloud so i was convinces it was the right setting. Sorry for my misconfiguration!
Configuring it with /webdav or /dav/files/USERNAME both work when set to OwnCloud.
