Is there anyway that I wont have to go back and forth to check if SimFly Client will decide NOT to track my flight after taking off?
Flew to destination for 2+ hours only to find that it was wasted flight.
I’m starting to get unmotivated to fly on SimFly. 
How can I prevent this from happening again?
Happened to me this morning.
Once you’re on the ground in the sim, before you start getting your plane ready, check the SimFly client Live data. If it has green like in the attached picture, you’re good to go. If not, close it, check task manager that its not still running in the background, and then reopen it.
Thanks. Seems to be another “checklist” to fly for fun on SimFly.
Has anyone else experienced this issue on a recurring basis?
If so please speak up so SimFly knows it’s not an isolated issue.
It’s likely going to take some in depth troubleshooting so I recommend setting up HWiNFO and Claude Desktop to help analyze what’s happening on your system when the issue occurs.
If SimFly can’t reproduce it, they will be entirely dependent on us to help fix it.
It’s typically the connection - simfly client is very fragile when it comes to connection all of a sudden you may have 15 min mission closure if connection was interrupted even shortly for couple of seconds few times.
Connection to SimConnect or connection to SimFly servers?
Simfly servers - at least thats what I think. I have occasionaly that problem but very rare I would say (Simfly mission cancelled invalidated)
Yes, It happen to me already 2 or three times , … and Just now again !
and if you click on red circular arrow to refresh the client :
Mission aborted, client failed?
@Karim-CTO-SimFly please can get real fix instead of usual " …will update you as soon as we have any news." and then, no news.
Keep those log uploads coming - even successful flight logs from borger and SxTx will be useful to narrow down the cause of the SimFly client failures.
Hi everyone,
I can confirm that we are still actively working on this issue to identify the exact cause.
The issue has not been forgotten or ignored; the investigation is still ongoing. As soon as we have a confirmed technical finding or a solution, I will update this thread accordingly.
Hello @Karim-CTO-SimFly
Are SimFly able to successfully reproduce the issue/error?
The logs have been shared to SF. Thanks for paying attention in investigating.
Now, I’m having issue connecting SF altogether after I saw potentially another instance of the flight not being tracked. So I tried refreshing the API key and now after several attempts, SF client refused to connect to the server altogether.
After almost 15 minutes, the client now connectible.
I have had two successive aircraft rental flights from ENVA to EHLE both fail with the “Your mission has been canceled!” dialog.
Not sure if the issues in the “Another bug” thread and the issues surfaced in this thread are related or not.
Curious if anyone else is receiving “Your mission has been canceled!”.
If so, is it occurring while airborne or after landing/engine shutdown? Also was it Unrestricted Flight mission or Aircraft rental.
I have successfully reproduced the error twice on successive flights, now trying to eliminate variables.
