You can try out the below setting to Troubleshoot the Timeout Errors.

1) Query Execution Timeout

You can increase the Query Execution Timeout by opening report into the BI studio

On Query Tab you will find the Timeout Text Box at the bottom left corner.

2) Report Execution Timeout

You can set the report to never timeout by setting the processing time out setting to ‘Do not timeout report execution’

If timeout is caused by length of the execution of the report then you change the Processing Option.

By default, the value is set to 1800 seconds

Either you can set for specific report or you can set value for all reports.

Follow this step to set value for specific report

Go to http://localhost/reports

Select the appropriate report and click on the report and choose "Manage" option.

Click on the tab "Processing Options" and choose the option "Report Timeout".

Follow this step for global setting

Go to http://localhost/reports

Click on "Site Settings" links at top

On the Site Setting Page, choose the "General" tab and choose the Report Timeout to "Do not timeout report"

3) HTTP Timeout

You can alter the value of attribute executionTimeout of tag httpRuntime, default value if 9000 and value is in the seconds.

<system.web>
    <httpRuntime executionTimeout = "9000" />
</system.web>

Open the Report Server’s Web.config file generally located at <Drive>:Program FilesMicrosoft SQL ServerMSRS10_50.MSSQLSERVERReporting ServicesReportServer
Locate the HttpRuntime parameter and alter the value. If it doesn't exist, you will have to create it within the section.

4) DatabaseQueryTimeout

You can alter the value for DatabaseQueryTimeout in the RSReportServer.config located at

<Drive>:Program FilesMicrosoft SQL ServerMSRS10_50.MSSQLSERVERReporting ServicesReportServer

The value of timeout is in seconds and default value is 120.

This value is passed to the System.Data.SQLClient.SQLCommand.CommandTimeout property.

where Name in ('SessionTimeout','SystemReportTimeout')

The default is 720 and it is in minutes.

`7)`SessionState Timeout

this require iis restart.

`7)`executionTimeout

this setting is asp.net related.

this setting found in the machine.config file located at <Drive>:WindowsMicrosoft.NETFrameworkv2.0.50727CONFIG

executiontimeout is in second and default value is 110 seconds.

report might be timeout from asp.net due to the large volume of the data, you can increase the value of maxRequestLength. size is in the mb.

this doesn't require system reboot.

I've consider the 64 bit version of SQL Server .

Hope this will help you.
