Error on scanning with Burp suite Professional v2020.6

Hi, after upgrading to v2020.6 I see the following issues: by selecting to scan one website ( default options, right click on the URL scan, 'Crawl and audit' ) the following will happen in most of the cases: 1. Scan (crawl and audit) will be queued and shown as task on the Dashboard 2. Scan (crawl and audit) will show the endless loop progress bar mentioning - 1 request ( 1 errors ) 3. Event log below will show the following message: 'Audit completed' The process will remain as it is even after several hours. Reverting back to version v2020.5.1 and loading the same project file will show no issues and the same action will proceed as expected.

Thanks for getting in touch. Is this happening with all sites or just certain ones? Would you be happy to send us some screenshots or a screen recording to support@portswigger.net to help us replicate the issue?

Hi, Updating here the appears when a website is using a different port other than 80/443 and the default options on Scan type for the protocol settings is selected. It seems that a probe will be send to check http/https (80/443) ports and if that is found to be closed the crawl will end immediately. Changing the Protocol settings to 'Scan using my specified protocols' will alter the behavior and the crawl will proceed normally with no issues. I hope this will help others as well.
