      Type Exception Report

      Message Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

      Description The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

      Exception

      Workaround

      1. Go to <confluence_install>/conf, and edit the server.xml file.
      2. Find all connectors your application is using. Just search for Connector in the file, or look at the example below. You're interested only in connectors whose protocol is set to HTTP and HTTPS (not AJP).
      3. Add relaxedQueryChars="[,]" to the connector properties in server.xml. For example: 
                <Connector port="26156" connectionTimeout="20000" redirectPort="8443"
                   maxThreads="48" minSpareThreads="10"
                   enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
                   relaxedQueryChars="[,]"
                   protocol="org.apache.coyote.http11.Http11NioProtocol"/>
      1. Restart Confluence
