Stuck in “estimating the connection quality” with RemoteDX Plugin

Posted on January 19, 2023

A user encountered an issue with RemoteDX where users were unable to reconnect to their disconnected Sessions on an RDS Farm and were stuck in "estimating connection quality". After uninstalling RemoteDX, the issue was solved when importing a Linux Load Balancer (HAProxy) Reg key. The user was thanked for this resolution and it was documented for reference. RemoteDX is not natively supported by RDS but is supported against Citrix/VMware Horizon/AVD. Documentation for RemoteDX can be found at https://support.controlup.com/docs/remote-dx-client-device-metrics.


Read the entire ‘Fixing RemoteDX Connection Issue for RDS Farm Sessions’ thread below:

Hi, after installing RemoteDX, users are not able to re-connect to their disconnected Session (RDS Farm). They stuck in "estimating the connection quality" and after some time they get "internal error". After uninstalling the RemoteDX, it works fine immediately . Any idea what’s wrong here with RemoteDX plugin?


Hi, it could be there is a network issue (blocked ports or NAT segregation) at play. I think it is best if you open a support ticket so we can have a session and check this together.


RemoteDX is supported against Citrix/VMware Horizon/AVD, at this time RDS natively is not supported. Here is a link to the documentation for RemoteDX. https://support.controlup.com/docs/remote-dx-client-device-metrics.

If RDS support for RemoteDX is something which interests you and your business, I would strongly encourage you to raise a Feature Request (native through console or via our support team)


Hi @member and @member, thanks for your inputs, but we found the root cause and the way how to fix it. For our RDS Farm, we are using Linux Load Balancer (HAProxy) which is not supporting UDP. Importing this Reg key fixed it.


Very happy to hear the issue is solved! I will document this tip for reference. Thank you
