Both Ignition 7.7 and Ignition 7.8 require Java 8 for the machine running the gateway - you might start there. ---

Thanks, 7.7 and 7.8 both require Java 8, it is correct but think mobile client works fine with Java 7. This information provided by Ignition support team. So previously with version 7.7, I am using java 8 and java 7 for mobile client. Same thing I had tried with version 7.8. Initially without installing java 7, I had tried mobile client with version 7.8 and found mobile client not working. So I had installed java 7 and tried using full path of java 7 but mobile client is not working and found “java.lang.Exception: Timeout waiting for new VM.” error. Could you please confirm that mobile client is working without java 7 ? ---

Today, I have done the fresh installation of Ignition 7.8 ( 7.8.0-beta1 (b2015090915) ) and JAVA 8 (Oracle Corporation 1.8.0\_60). I have created new project for testing the Mobile Client. While launching the mobile client from launch link provided on home page below error occurs. Please suggest. ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/f/f52dc29bf6943e85b84f941d08f12f5ca811677b.JPG) ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/6/67a41755548fbb483348cd881c56fbc3f2ca9827.JPG) ---

Would this gateway happen to be running on a headless linux? If so, refer to this: [https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/33/0/running-the-mobile-module-on-linux](https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/33/0/running-the-mobile-module-on-linux) Upgrading Ignition might have written over your Ignition.sh if you had made this fix in a previous version. ---

I’m running 7.8.2 and I still have this issue… anyone found a solution? as you can see I had to restart 6 times and after that finally I made a successful connection. this it the only thing stopping me from using the mobile project right now. any help would be appreciated. Sometimes it works the first try sometimes it doesn’t… I really don’t know whats going on. ![:scratch:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/76d1620bec252bfac07050c889ff5a91dc8a9c25.gif ":scratch:") ---

Hmm… this is odd, this issue was fixed in 7.9.8 if I’m not mistaken. I haven’t had this happen to me in a while. ---

Yes, I have to use IE11 as a client on customer`s PCs for some time . “Clearing cookies when my IE shutdown” in my post should be read as “Delete browsing history on exit” in IE Properties. When tip is enabled I establish communication immediately.
