Issue looks like a duplicate of https://jira.atlassian.com/browse/JSDSERVER-6012.

JSDSERVER-6012 has been fixed with fixversion of 3.16.0 and 3.15.3.

Guys, this is not only for existing Customers and wrong credentials. Even the hint for Password Policy is not showed. That mean, I am new Customer and I do input of not enough strong or too strong password, I do not receive any message what is wrong and why I cannot enter the Service Desk. Guys, this is crucial, my customer cannot invite customers! Meaning, they are not able to use Service Desk purpose! 

Please ensure that a fix for this is released for the 7.x product, as many of us in an 'enterprise' context will not upgrade to 8.0 until its well bedded in.

Please update this case.

Our Customer wants to buy more Jira Service Desk Licenses but put this on hold until this is fixed.

Any update when this will get Triaged please?

Please have a look upon this bug! It is a serious problem for customers, whereas it hinders delivering efficient support + communication.

We are also affected by this but are on 3.15.0

Also we have a similar problem when resetting password, where the error that the new password does not meet the complexity requirements is not shown.

I'd like to stress that there is literally no warning to the user that something is wrong. This causes major detrimental impact to customers of your clients as they believe their service desk is not responding, which either causes disruption as people contact the company directly, or they don't bother reporting / checking issues.
