# Troubleshoot the Connector

This section describes how to troubleshoot common problems that might occur when you set up the SharePoint Remote Connector.

Error: HTTP414 Request URI too long

This error can occur when the Internet Information Services (IIS) web server refuses to accept long URLs. To resolve this issue, update the `web.config` configuration file for the SharePoint site in IIS. For example:

    <configuration>
        ...
        <system.web>
            ...
            <httpRuntime ... maxUrlLength="1024" ... />
            ...
        </system.web>
        ...
    </configuration>

Timeout Error when Synchronizing User Profiles

When you use the connector to synchronize user profiles, you might see exceptions such as:

`System.TimeoutException: The HTTP request to 'http://[sharepoint/resource]' has exceeded the allotted timeout of 00:00:20. The time allotted to this operation may have been a portion of a longer timeout.`

You can prevent this error by increasing the timeout on the SharePoint system. To do this, alter the relevant fields in `web.config`. For example, to increase the timeout to one minute, modify the fields as follows:

    <binding name="ProfileServiceHttpsBinding"
        receiveTimeout="00:01:00"
        sendTimeout="00:01:00"
        openTimeout="00:01:00"
        closeTimeout="00:01:00">

    <binding name="ProfileServiceHttpBinding"
        receiveTimeout="00:01:00"
        sendTimeout="00:01:00"
        openTimeout="00:01:00"
        closeTimeout="00:01:00">

    <binding name="ProfileDBCacheServiceHttpsBinding"
        receiveTimeout="00:01:00"
        sendTimeout="00:01:00"
        openTimeout="00:01:00"
        closeTimeout="00:01:00">

    <binding name="ProfileDBCacheServiceHttpBinding"
        receiveTimeout="00:01:00"
        sendTimeout="00:01:00"
        openTimeout="00:01:00"
        closeTimeout="00:01:00">
