"This browser is not supported by Splunk"

[sylim_splunk]

I'm using Splunk version 6.6.4 and installed the latest version of Chrome, firefox and IE available as of this writing. Strangely since last week none of users except one, "mySplunkID" can login to Deployment server SplunkWeb. Error on the browser is "This browser is not supported by Splunk" - attached below;

Why is it happening all of a sudden?

Hi

I have the same issue. I can't to put screenshots, pity.
But when i go to the server, the common.js is there. So i don't understand why that's says it can not find this file.

Should I replace it with a new common.js? Where can i found this file ?

Thanks

This turned out to be a case of one of java script file missing for unknown reasons. HAR dump showed us some hints about the issue.
There was a 404 error for a request as below;

After recovering common.js which was producing error in the screenshot, the issue has gone away. For some reason the file disappeared. Try to find 4xx error in HAR dump same thing could happen if some of files were deleted accidentally.

Hi i have the same issue.
But Can you explain how can we resolva that ?

I have already common.js in my server.

This was caused by a missing file which is being called during page loading. Firstly confirm if it's happening regardless of browser types then you might hit potentially the same issue.
Then enable debug mode for example in chrome, https://developers.google.com/web/tools/chrome-devtools/?utm_source=dcc&utm_medium=redirect&utm_camp... to find any 400 errors as illustrated in the picture above. But still it could be a different issue but this is the way how you can troubleshoot it.
