"Unable to upload", yet the file is uploaded...

[stefanoquintarelli]

Hello, I'm runnig nextcloud 16.0.3, (with TOTP), thunderbird 60.8.0, filelink 1.8 on windows 7

when uploading a file, I always get an error message
"Unable to upload: to "

but when I log in to my server, the file is there. it has been uploaded.
(so I think there's not a credentials problem)

any ideas of what I could try ?
any help highly appreciated.

@stefanoquintarelli I can confirm this issue. Running Nextcloud 16.0.3, Thunderbird 60.8.0 (32bit), Windows 10 here.

File is uploaded to the server, but I got an error within Thunderbird like shown below in the screenshot.

So the issue here seems to be the "TOTP" setting.
I'm running Nextcloud 16.0.3 & Thunderbird 60.8.0 (64bit), but without "TOTP" and filelink still works perfectly fine.

Like @creopard mentioned we do not have the "TOTP" running on this Cloud server and nevertheless it isn't running here.
