Hi Nick,
thank you very much for the quick reply. That sounds promising. I have seen your pull request #413. So can we expect in the next guacamole release a way to modify the TcpAckTimeout? That would be gorgeous! - Martin On 2023/02/15 16:07:44 Nick Couchman wrote: > [cid:audit_bf_rz_21_DE_RGB_65712845-2146-4396-8f42-bcd2b1e8317e11.jpg] On Wed, Feb 15, 2023 at 3:17 AM Dyck, Martin (BITBW) < > martin.d...@bitbw.bwl.de<mailto:martin.d...@bitbw.bwl.de>> wrote: > > > Hi, > > > > thank you for providing Apache Guacamole.
