xrdp_iso_send: trans_write_copy_s failed - Issues rdp from RaspiOS to Arch x86 when using Remmina

I am trying to setup rdp from my rpi 4 with Raspberry pi OS to my laptop running Arch Linux using Remmina. Currently I cannot rdp from my rpi into any Arch machines (there are two) using Remmina. However, using rdesktop as a client does work. rdesktop is an undesirable solution, as I wish to have access to the features of Remmina and potentially run Remmina straight from X in some kind of makeshift kiosk mode. This is the offending error on Arch VM/BM when running watch systemctl status xrdp during a connection attempt from the rpi to the Arch machines with Remmina: May 05 23:51:30 zion xrdp: [INFO ] xrdp_load_keyboard_layout: keyboard_type keyboard_subtype May 05 23:51:30 zion xrdp: [INFO ] xrdp_load_keyboard_layout: model [] variant [] layout [us] options [] May 05 23:51:30 zion xrdp: [INFO ] TLS connection established from 10.0.0.94 port 43248: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 May 05 23:51:30 zion xrdp: [INFO ] xrdp_caps_process_pointer: client supports new(color) cursor May 05 23:51:30 zion xrdp: [INFO ] xrdp_process_offscreen_bmpcache: support level 1 cache size 7864320 MB cache entries 2000 May 05 23:51:30 zion xrdp: [INFO ] Loading keymap file /etc/xrdp/km-00000409.ini May 05 23:51:30 zion xrdp: [WARN ] local keymap file for 0x00000409 found and doesn't match built in keymap, using local keymap file May 05 23:51:31 zion xrdp: [ERROR] xrdp_iso_send: trans_write_copy_s failed May 05 23:51:31 zion xrdp: [ERROR] SSL_shutdown: Server closed TLS connection May 05 23:51:31 zion xrdp: [ERROR] Sending [ITU T.125] DisconnectProviderUltimatum failed ---------- I have 4 machines: - Windows 10 Lappy - Arch Linux in a VM - Arch Linux on "Bare Metal" - Raspberry pi OS on rpi "Bare Metal" Here are the success/failure scenarios that I have experienced thus far, which have been repeated and confirmed: |Result|Source|Session Protocol|Destination| |------|------|----------------|----| | PF | ALL | vnc over rdp | rpi| | PF | ALL | xorg over rdp | Arch VM/BM| | S | Win10 | xorg over rdp | rpi| | S | rpi | standard rdp | Win10| | S | Win10 | vnc over rdp | Arch VM/BM| | S | Arch VM/BM | standard rdp | Win10| | TF | rpi | n/a | Arch VM/BM| | S | Arch VM/BM | xorg over rdp | rpi| - S = success - TF = total failure = connection drops before session manager can illicit credentials - PF = partial failure = no window manager started and only backgound of session manager persists - ALL = all machines - VM/BM = Virtual Machine / Bare Metal Despite the xorgxrdp package being installed on Arch VM/BM I cannot start an Xorg session. The most important thing here is establishing an rdp session FROM my rpi to my Arch machines, as the rpi is running as an rdp portal of sorts. I have tried turning off xrdp-sesman to see if that at least results in establishing a connection. My thinking there was maybe it's only the session manager having problems, which assumed the connection is made separately. This configuration does not work, no connection appears possible. ---------- ### Arch Linux VM/BM system/app info (identical systems) ### xrdp version: xrdp -v xrdp 0.9.16 A Remote Desktop Protocol Server.
