Login Session Expired

[Roughneck]

Still getting "Login Session Expired" message.  Game closes afterwards.  I'm not logged into any other machines for the game.  I have my account saved on my iPad for the forums.

I had the same experience today. What is it about?

This really sucks when working in the mission editor. Why is there even this continuous login check when ED says 99.999999999999999999999999% of the player base is single player?

I play single player exclusively... I don't have the time to finish 2 hour long missions in one sitting. So I'll leave the game open mid-mission after playing for a bit to come back to it the next day and continue, but then I get this error which closes the game and forces me to start the mission over.

Found this in the logs:

@BIGNEWY any guesses as to why we're still getting this error?  4 of us (that are reporting it) got this over the weekend.

I used to be able to suspend the pc during a campaign mission to finish it later or the next day, which was a neat feature, but it's impossible now...

I've reported this issue in February. It's been wishlisted. Easy workaround would be to enter offline mode before starting the mission. If you forgot to do that, there's another use at your own risk workaround: Before suspending your computer, add a firewall rule or invalid network route that prevents further communication with the DCS master server. While this sounds counterintuitive, DCS will only terminate itself after it reconnects to the master server. It will happily live on without the master server, at least for a couple of hours. Haven't tried that overnight, yet.

Update: Tested with the dedicated server, which runs for more than 3 days after losing connection to the master server. I'd assume the client will also.

I just had this happen again...it's getting kinda old.  No rhyme or reason as to when it happens, or how often.  @BIGNEWY is it possible for you to push this issue up the support team chain of command?  I know they have their hands full with the latest update and release of the Corsair...but I was in the middle of binding controls for the Corsair and the game closed out.

[BIGNEWY]

Hi, 

this has already been sent up the chain, but there is no clear reason, most of the time it is due to ISP session changes or local internet issues which are outside of our control.

That's a bit like blaming the road if your car's engine stops every time you hit a pot hole. Not an ideal situation, but a proper car should be able to deal with it.

The DCS client and master server should simply be more resilient to less than ideal internet connections. Even if a session check with the master server fails, the client should try to reauthenticate Instead of just terminating. That should be a relatively straightforward change that'll make a lot of paying customers less frustrated. I've litigated the issue in detail here (first post updated since you reported it to the team):

I see this phrase repeated quite often on these forums, first its redundant (as how can you be a customer if you have not paid), and second it has an entitled ring to it ... just "customer" will do.

To me this issue is 100% reproducable. Just suspend the PC with DCS running. Upon wakeup, DCS will exit with this error.

Maybe it depends on the PC Bios, perhaps it makes the network adapters sleep?  I'm pretty sure that my PC has gone into suspension while I'm editing missions and have gone to lunch, but have never got that session expired message.

[winghunter]

Maybe, however DCS is the only game / sim with this issue.
