Hi,

Today I accedentily connected Kibana 6.7 to Elasticsearch running 6.5 but after this normal users are not able to log in anymore from the main kibana 6.5 instance. The error is: Oops, error. Try again.

The admin account has no problems logged in.

I checked and found there now are to kibana indeces, .kibana\_1 and .kibana\_2. Could this be the problem and if so, how can I correct this?

Yep that would be it.  
Try changing the `.kibana` alias to the older index of the two.

Actually the alias is already pointing to the oldest index (older by 30 seconds, .kibana\_2). I tried changing to alias to kibana\_1 but that results in an error when trying to access Kibana. I was lucky to have a window open to change the alias back.

`{"statusCode":500,"error":"Internal Server Error","message":"An internal server error occurred"}`

What else can I do?
