TimeOut in Transmission from xxx.com

linda | Last updated: Feb 27, 2017 03:25PM UTC

It works well at first. But after a few hours, there are many errors and when checked in Alerts tabs it says "Timeout in transmission from xxx.com". I can access the application without any issues by using my browser without the burp proxy. But if I use the Firefox with burp proxy to access the application, all the pages are loading very slowly. Sometimes it will not able to access and then it says timeout. Now I have throttled Number of threads from 20 to 10, but the issue still exists. What can I do to solve this issue? Now the scanning is very very slow and I think it will be abandoned due to too many errors...Please give any advice ASAP.

Hi Linda Thanks for your message. The timeout occurs when the server does not respond to a request from Burp. You could manually check each request using the Logger++ extension. This may help you determine what is causing the timeout. When you are scanning the application and Burp is producing this alert, can you still access the application manually using your browser? Is the application still responsive?

Hi Liam I am scanning the application now. And I can still access the application manually using my browser and the application works well. I have installed the Logger++ extension. But I do not see any error about the timeout. Now about 50% requests time out, and this requests may not have response so that it may not be reported in the Logger++ Tab.
