症状

• Unable to add more than a certain number of users to any project role
• Running JIRA behind a Proxy, eg. IIS
• This is the error being returned when attempting to add more users to Project Role: "The JIRA server was contacted but has returned an error response. We are unsure of the result of this operation"

原因

Every time a new user is added to a project, that username is also added to the url. The problem is the request url is longer than the max allowed query string configured for IIS.

ソリューション

• Increase the maximum query string for IIS from 2048 (default) to 4096 bytes.
