When I put in the username and password it gives the following error “java.netSocketException: Software caused connection abort: socket write error and then a restart button down the screen – it just goes back to the login screen then. ---

There is a bit more information that you would need to supply about your version of Ignition and what Java version(s) are installed on your machine ( if you know how to determine that at this point ). It might also be helpful to know which mobile device and the OS (IOS/Droid/Etc.) you are using. I can guess that the version of Ignition is under 8, because Mobile is replaced by Perspective at that Ignition version- though things change at version 7.9.10. There are some settings in TLS/SSL and Authentication that can also cause the error, because security has changed. If you are in a hurry, you may wish to read the support policies then contact support at ( no colon here means no emoji ) `https://support.inductiveautomation.com` and you may also wish to look at ( no colon as before ) `https://www.azul.com/products/zulu-enterprise/jdk-comparison-matrix/` and `https//forum.inductiveautomation.com/t/configuring-db-connection-for-windows-authentication-causes-jvm-to-crash/27757` and Just Google the word ‘OAuth’ and Best of All ( no colon as before ) `https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/87/0/running-multiple-versions-of-java-on-the-same-windows-machine` ---

Ignition v7.9.10 Java v8 IOS (ipad and iphone) ---

Then this may help `http://forum.inductiveautomation.com/t/client-login-failover-when-ldap-not-available/21204` which refers to `https://docs.inductiveautomation.com/display/DOC79/User+Sources#UserSources-MainProperties` User admin Password password all lower case - I would guess that you already tried that, checking your caps lock key / indicator. In other words, something about the use of AD or SSL / TLS /Authentication has likely changed. This was done in Ignition 7.9.10- so did this work in 7.9.10 before recently? ---

There is no issue logging in when using laptop so think its more to do with mobile client. We have been using 7.9.10 for few months I honestly don’t know if its just since 7.9.10. one our customers contacted me when setting up ipad to say she was having issues. I would always be using the laptop ---

The mobile client should work better _without_ Java on it, because the idea was that it would use HTML5 and AJAX to connect through a local WiFi connection. If the client has both IOS and a Java system on their tablet/phone, they may get different results with the cellular connection turned off and the Java system temporarily defeated ( reboot usually required ) from the PLC locale than away at home. The use of ‘Authentication’ ( as in OAuth /OpenID or ‘Secure ID’, SAML etc. ) was supposed to take place in Ignition 8, yet TLS and SSL may have been changed earlier- that would be around 7.9.10. I made some posts earlier about my own problems with Login when AT&T decided that users must ‘Authenticate’ for their mail system. If this was done, or the IOS version updated- it might explain the login failure. That is why you might try Inductive Automation support section through e-mail. The website is ( drumroll ) `https://support.inductiveautomation.com` then check policies- your organization may have priority e-mail support. They may or may not find it easier to start with this thread. Use triple marks in your mail using the character above the tab ( usually the same key as the curvy tilde to the left of the number 1 ) to avoid immediate use of the link. That could also be cut and pasted from `http://forum.inductiveautomation.com/t/java-error-with-mobile-ignition/27825/4` yet they might need to logon to the forum and open a word-processor program to capture what has been said. Much of it is at `file:///C:/Users/jlivingston/Desktop/IgnitionTrng/Ign79Man/DOC79/About-Mobile-Clients_6046597.html` on my machine- your path to a downloaded 7.9 manual would be similar. ---

Troubleshooting the old mobile module can be difficult, it might be best to call into support. ---

Yes, I have mentioned that twice. What I have not said is that there are multiple versions of everything Apple, for example `file:///C:/Users/jlivingston/Desktop/IgnitionTrng/Ign79Man/DOC79/Mac-OS-X---Install_6045896.html` goes into Java 8+. At the current time, Oracle has various versions of Java in that range for commercial and non-commercial users. How this interacts with any Internet or Telephone provider can mean for a lot of guessing, and further questions. It would be best to get it in writing if you need evidence of your efforts.
