Burp Collaborator No Connections

yancangyun | Last updated: Jun 15, 2021 08:36AM UTC

Hi,excuse me. When I use the Burp Collaborator with the default Collaborator server. The health check shows: Server address resolution Success Server HTTP connection Warning Server HTTPS connection (trust enforced) Warning Server HTTPS connection (trust not enforced) Warning Server SMTP connection on port 25 Warning Server SMTP connection on port 587 Warning Server SMTPS connection (trust enforced) Warning Server SMTPS connection (trust not enforced) Warning Polling server address resolution Success Polling server connection Error No connections to dvc6jiypy3el8ytc9nnduja1asg5uoe6i97.burpcollaborator.net could be opened. The collaborator may still work, as long as the server under test can connect to this port. No connections to the polling server at polling.burpcollaborator.net could be opened. The collaborator will not work in this configuration. I donot know what should I do to solve this problem. Thanks for your help.
