Running Roon On Win 11 24H2 IoT LTSC
Firstly, thank you - RoonLabs team, for this major update - and for all the work that went into it.
I also had trouble on getting Roon Mac client (on 26.4.1) to connect with Titan on applying both updates.
Is it a known problem that to launch both updates at the same time causes Roon when it’s ready to hang and necessitate more even than a soft reboot from the Web GUI; and that the only way to get Remote Version 2.65 (build 1653) to see and connect to Titan is by removing the latter’s power cable and re-inserting it?
Hello @Mikael_Ollars ,
Thanks for your report and sorry to hear about the issue. Can you please use these instructions to access your RoonServer + Roon logs, upload a set to our uploader and let us know once uploaded? Thank you.

Done Noris, took the logs from RoonServer and Roon. However, they dont seem to say much..
Another reboot of the Windows server this morning, and weirdly, now RoonServer started up!?
Caused another Err in the EventLog though:

And, even though i don’t care/need it Roon client will not start up in the Remote session.
(Same crasches as posted first)
Anyways, you should be able to see/get logs from the RoonServer now!
Thanks for sending those over @Mikael_Ollars! Our team will take a closer look and should have more information to share before the end of the week.
Thank you!
