Intermittent issue where user see's an error and must click the connection link a 2nd time

[DHaussermann]

There is an intermittent error where users must click the connection link a 2nd time. On the 1st attempt the new tab shows the message about needing to connect the user first.
Clicking the link a 2nd time then works as expected.

Unfortunately there is very little info on how prevalent this issue is. The issue may be HA related.
Most extensive testing showed it occurred 2/10 time on a server with 2 cluster instances.

What was determined is that issue does occur on v1.0.1 and is not new to upgrading to version v2.0.0

Maybe requires a separate issue but on occasion the following error can also occur in similar conditions.
