-------------------------------------------------------------------------------------------------

The "(400) Bad Request" error is most often seen due to the HTTP request header exceeding the default max limit (16384). This can happen when the client is a member of many groups in the domain, causing the group's information to be included in the request and causing a long request header.
 

Environment

All supported operating systems

Resolution

1). Locate the server.xml file, [server install dir]\tomcat\conf\server.xml .
2). Locate maxHttpHeaderSize size setting for Spotfire app:
    < Service name="Spotfire">
        <Connector port="80"
               maxHttpHeaderSize="16384"
               …
3). Change this setting to 65536:
maxHttpHeaderSize="65536"

4). Save the file.
5). Restart the TIBCO Spotfire Server Windows Service (Start -> Administrative tools -> Services…).

NOTE:
On the Spotfire server, changing the maxHttpHeaderSize setting has proven effective. 

Issue/Introduction

Spotfire Professional login error. The remote server returned error: (400) Bad Request.

Additional Information

If this is due to the request header exceeding the default max limit, the solution for this is to set higher max limits for "MaxFieldLength and MaxRequestBytes" in the registry, using instructions from "http://support.microsoft.com/kb/820129"
