Try disabling glyph caching (I algo have disabled bitmap and off-screen caching on my connections.)
See: https://github.com/FreeRDP/FreeRDP/issues/6258 It looks like in Guacamole 1.4.0 they are disabling the caching. https://issues.apache.org/jira/browse/GUACAMOLE-1191 -Jonathan Hankins On Thu, Sep 23, 2021 at 5:11 AM Jose Moreno Delgado <[email protected]> wrote: > This error appear as well: > > guacd[76730]: ERROR: Connection closed. > guacd[76730]: INFO: Internal RDP client disconnected > guacd[76730]: INFO: User "@c30491ee-9957-46e4-9eb3-4b7778271b04" > disconnected (0 users remain) > guacd[76730]: INFO: Last user of connection > "$18e70f32-9815-4804-a651-330ddbaf4250" disconnected > guacd[6]: INFO: Connection "$18e70f32-9815-4804-a651-330ddbaf4250" removed. > guacd[76918]: ERROR: User is not responding. > guacd[76918]: INFO: User "@00d1360e-2a61-4a4b-a22f-c397ab247c5b" > disconnected (0 users remain) > guacd[76918]: INFO: Last user of connection > "$8b84d2fd-b9c0-48ae-96fd-02a69295c9ef" disconnected > guacd[77073]: ERROR: User is not responding. > guacd[77073]: INFO: User "@089ef6d6-7c51-43d0-99af-1024b776a9c1" > disconnected (0 users remain) > guacd[77073]: INFO: Last user of connection > "$8eca4cc8-e2e5-4217-ac4c-c9bdfd569502" disconnected > guacd[77073]: INFO: Internal RDP client disconnected > guacd[6]: INFO: Connection "$8eca4cc8-e2e5-4217-ac4c-c9bdfd569502" removed. > guacd[76918]: INFO: Internal RDP client disconnected > guacd[6]: INFO: Connection "$8b84d2fd-b9c0-48ae-96fd-02a69295c9ef" removed. > > ------------------------------ > *De:* Jose Moreno Delgado <[email protected]> > *Enviado:* jueves, 23 de septiembre de 2021 12:03 > *Para:* [email protected] <[email protected]> > *Asunto:* RE: RDP disconnects when a second user starts a different RDP > session in a network device > > Hi, > > Just error appeared right now, this is the log where the error appears: > > guacd[6]: INFO: Creating new client for protocol "rdp" > guacd[6]: INFO: Connection ID is "$9a07f3ca-25c5-48ea-b057-499f6c48cb1c" > guacd[77025]: INFO: Security mode: Negotiate (ANY) > guacd[77025]: INFO: Resize method: none > guacd[77025]: INFO: User "@9cf4b6f7-8255-445f-a23c-d1abe6e33f88" > joined connection "$9a07f3ca-25c5-48ea-b057-499f6c48cb1c" (1 users now > present) > guacd[77025]: INFO: Loading keymap "base" > guacd[77025]: INFO: Loading keymap "es-es-qwerty" > guacd[77025]: INFO: Connected to RDPDR 1.10 as client 0x9645 > guacd[77025]: INFO: RDPDR user logged on > guacd[77025]: ERROR: Connection closed. > guacd[77025]: INFO: Internal RDP client disconnected > guacd[77025]: INFO: User "@9cf4b6f7-8255-445f-a23c-d1abe6e33f88" > disconnected (0 users remain) > guacd[77025]: INFO: Last user of connection > "$9a07f3ca-25c5-48ea-b057-499f6c48cb1c" disconnected > guacd[6]: INFO: Connection "$9a07f3ca-25c5-48ea-b057-499f6c48cb1c" removed. > guacd[6]: INFO: Creating new client for protocol "rdp" > guacd[6]: INFO: Connection ID is "$8eca4cc8-e2e5-4217-ac4c-c9bdfd569502" > guacd[77073]: INFO: Security mode: Negotiate (ANY) > guacd[77073]: INFO: Resize method: none > guacd[77073]: INFO: User "@089ef6d6-7c51-43d0-99af-1024b776a9c1" > joined connection "$8eca4cc8-e2e5-4217-ac4c-c9bdfd569502" (1 users now > present) > guacd[77073]: INFO: Loading keymap "base" > guacd[77073]: INFO: Loading keymap "es-es-qwerty" > guacd[77073]: INFO: Connected to RDPDR 1.10 as client 0x727a > guacd[77073]: INFO: Connected to RDPDR 1.10 as client 0x527a > guacd[77073]: INFO: RDPDR user logged on > > Is there something to check? > > ------------------------------ > *De:* Jose Moreno Delgado <[email protected]> > *Enviado:* jueves, 23 de septiembre de 2021 9:25 > *Para:* [email protected] <[email protected]> > *Asunto:* RE: RDP disconnects when a second user starts a different RDP > session in a network device > > Let us check, because we noticed that we had caching enabled (bitmap, > off-screen, glyph), we're connecting mainly to windows server 2003, 2008 > and 2012 machines because of the systems embedded and it looks like this is > more stable, we will check logs and if problem persists we will share > logging information to drill down in the problem. > > ------------------------------ > *De:* Mike Jumper <[email protected]> > *Enviado:* martes, 21 de septiembre de 2021 16:50 > *Para:* [email protected] <[email protected]> > *Asunto:* Re: RDP disconnects when a second user starts a different RDP > session in a network device > > On Tue, Sep 21, 2021 at 4:58 AM Jose Moreno Delgado <[email protected]> > wrote: > > Hi, we have a stable Guacamole solution running properly, but we have > noticed that when a user is connected to a device through RDP and a second > user runs a new RDP session (same or another device) drops and reconnect > message appears in the screen of previously connected users.
