Hi All, Recently upgraded from 8.1.7 to 8.1.8 As a result I get the following error when launching some (not all) vision clients on site (all have been updated to the latest). This happens at the opening of the main login window immediately after the splash screen finishes pulling the project As my laptop is one of them I am trying to get to the bottom if it. - I am able to click ok and everything seems to work? That I can see so far… - It happens every launch - It DOES NOT come up in the visionclientlauncher.log file - I have tried blowing the cache away but it made no difference. Any Ideas? As always **thank you** in advance for any and all help ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/5/25848f386d785a3c7bbb2ce6b213c787b251aab9.png) ```auto 09:22:16.570

Can you post the full client logs? Or contact support. Something isn’t being created that should be, which should mean that anything your client is doing with tags would fail. ---

Hi there! Any updates with this issue? Exactly the same behaviour here… Thanks! ---

Yes. Looks like there is a problematic Auto login Script that was made by my predecessor which manages some cool features for our client terminals. It works, but throws this fault up because of the way it works - so I need to revise it - but it does not seem to be causing an actual issue with the runtime I am using (in this case). Looks like the latest update just highlighted the fault in a new and exciting way! To see off you are having the same issue - you could try what support got me to do go to designer and turn off auto login, see if it goes away. (image below) Else contact support - they were ace. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/c/6c5703918dc906c140cd708cc037f662963ac9a3.png) ---

I have the same problem. Is it resolved?

Hello, Has there been any update regarding this issue? In my setup, I verify user accessibility against a database — if a user is marked as disabled, the login is denied as expected. However, when attempting to deny login for a user **not present in the database** , I continue to encounter the same error after the _“Access Denied”_ message and logout process. Could you please advise if there has been any progress or recommended workaround for this scenario? Thank you in advance, Namratha
