Jelo: Mabye a proxy which is serving you an old response (no update available)? I have no other explanation as I can prove here that it is working properly.

Edit: The weird thing is that we did not change anything in the backend regarding this.

I might find the time to look into the codebase to see if something was changed in the updateroutines with the release of LS2.05+ 150708. I am not pushy on that issue. I am used to update manually and via comfortupdater. And at least 2.06+ 150730 was able to update to 150731 via Comfortupdater it might be only a small group of installations which no longer see updates.

since 150730 , LimeSurvey use a totally new ComfortUpdater, calling a different server : comfortupdate.limesurvey.org

Thanks, that might help finding a difference between these two update servers when it comes to incoming connections.
It still might be a change in the codebase to 150608 on LS2.5+ which was carried on till the complete rewrite of the comfortupdater.

Dennis - that's what I've been trying..

I ask with HTTPS : maybe your CA in your server are not updated with Comodo

sorry about that - same result when trying wget update.limesurvey.org

I set 'debug'=>2 on line 67 of application/config/config.php and receive the following output when trying to update
