kio_sftp_www_to_wwwlogs.log: Full kio_sftp debug output while opening
sftp://IP/www and clicking into wwwlogs; shows parallel jobs and immediate
refusal/hang
Summary:
Dolphin sftp: navigating from /www to /www/wwwlogs fails with "Connection
refused/Access denied" or hangs; direct URL sometimes works
Description:
On Kubuntu 24.04 (Plasma 5.27.12, KF 5.115.0, Dolphin 23.08.5, Qt 5.15.13),
navigating a remote host via sftp shows unstable behavior. Opening
sftp://IP/www lists fine, but clicking into sftp://IP/www/wwwlogs often causes
"Connection refused"/"Access denied" in the UI, or prolonged "Opening…" hang.
Directly opening sftp://IP/www/wwwlogs sometimes works. SSH/terminal sftp
works; sshfs works reliably.
Steps to Reproduce:
1. Start Dolphin with logging.
2. Open sftp://45.144.178.11/www
3. Click into "wwwlogs"
4. Observe error "Connection refused"/"Access denied" or hang "Opening…"
Observed Result:
- kio_sftp spawns parallel jobs (listing + statfs/free space). One job
immediately fails with Connection refused; UI shows denial or hangs. See
attached logs.
Expected Result:
- Seamless navigation from /www into /www/wwwlogs without reconnect/refused
state.
System Information:
- Plasma: 5.27.12
- Dolphin: 23.08.5
- Qt: 5.15.13
- KDE Frameworks: 5.115.0
- kio: 5.115.0-0ubuntu6
- kio-extras: 23.08.5-0ubuntu5
- libssh: 0.10.6-2ubuntu0.1
- OpenSSH server: OpenSSH_9.6p1 (Ubuntu), OpenSSL 3.0.13
- Distro: Ubuntu 24.04 (Kubuntu)
- Server reachable; authentication succeeds; sshfs works reliably.
Additional Notes:
- Disabling previews/free space polling reduces frequency but not fully.
- Prior sftp tabs/history exacerbate reproducer; clean profile still shows
issue.

- kio_sftp_www_to_wwwlogs.log
