Can someone happen to let me know what the maximum value that can be set for maxRequestLength in the SSRS web.config file. I currently have it set to 2097151 but if I increase it any further the SSRS Reports homepage stops working and just displays "Error" I have restarted SSRS through the service as well as the config manager but nothing seems to work, can anyone assist? The location of the file that I am editing is "C:\Program Files\Microsoft SQL Server\MSRS12.MSSQLSERVER\Reporting Services\ReportServer"
Thanks
I have found what was the issue, though I had set the maxRequestLength within the relevant config files in SSRS, I had to also amend the Limit Size set in IIS for the SMTP, once I had increased the size here everything worked fine.
I think there was some initial confusion on the error message due to getting a similar one before based on the config file.
