Linux Workspace App and Citrix Virtual Apps do not work together after upgrading Citrix Windows Servers' OS to Windows Server 2019


Adrian Torregrosa

Question

We have an environment with the following setup which works fine:
CTXDC:
  Windows Server 2012
  Citrix Virtual Apps 7 1912 LTSR - Virtual Apps 1912.0.0.24265
  Citrix Virtual Apps and Desktops 7 1912 LTSR - Storefront 1912.0.0.40
  Citrix Workspace 1912 - 19.12.4000.19
VDA:
  Windows Server 2012
  Citrix Profile management 19.12.3001.7
  Citrix Virtual Apps and Desktops 7 1912 LTSR - Virtual Delivery Agent 1912.0.0.24265
  Citrix Workspace 1912 - 19.12.4000.19
Linux Client:
  RHEL 8.4 ICAClient 22.5.0.16

 

In another environment, which had the same setup as above, we upgraded the Windows Servers to Windows Server 2019, and after doing so the setup did not work anymore
CTXDC:
  Windows Server 2019
  Citrix Virtual Apps 7 1912 LTSR - Virtual Apps 1912.0.0.24265
  Citrix Virtual Apps and Desktops 7 1912 LTSR - Storefront 1912.0.0.40
  Citrix licensing 11.17.2.0 39000
VDA:
  Windows Server 2019
  Citrix Virtual Apps and Desktops 7 1912 LTSR - Virtual Delivery Agent 1912.0.0.24265
  Citrix Profile management 19.12.3003.11
  Citrix Workspace 1912 - 19.12.4000.19
Linux Client:
  RHEL 8.4 ICAClient 22.5.0.16

 

Trying to launch a generated .ica file from the client, with PrintLogThreshold=6 inside it, returns
Terminate command fromm server:TERMINATE_LOGOFF
I generated some logs on the client side and to my understading, it appears the the server is telling the client to indeed terminate the session:
citrix-wfica: ----------------- RCV 5 (1) --------------------
citrix-wfica: channel = 63, length = 3, compressed = 0, completed = 2, Blocknr = 1

citrix-wfica: V3Reducer: EXIT bytes consumed = 3, inString = 0

citrix-wfica: PdRFrame: DeviceWrite, bc 11, Status=0x0
citrix-wfica: SEND TERMINATE ACK

 

Using the same .ica file from a Windows Machine of the Domain works.

 

I haven't been able to identify why is the server, if it indeed is, actively closing the connection.

 

Any hints?

 

Thanks in advance.
