hi there I am trying to use burp collaborator and unfortunately it is not polling data. I tried to make health check and got below results : We communicated with the collaborator, and appeared to successfully record events, however when we attempted to retrieve the interaction records the expected records weren't present. Initiating health check Server address resolution Success Server HTTP connection Success Server HTTPS connection (trust enforced) Success Server HTTPS connection (trust not enforced) Success Server SMTP connection on port 25 Success Server SMTP connection on port 587 Success Server SMTPS connection (trust enforced) Success Server SMTPS connection (trust not enforced) Success Polling server address resolution Success Polling server connection Success Verify DNS interaction Error Verify HTTP interaction Error Verify HTTPS interaction Error Verify SMTP interaction Error Verify SMTPS interaction Error

Same issue for me. I've been searching for tangible information for a while on this now too. Private Collaborator instance on an internal network . All tests pass except the "Verify" ones. All default ports. Having some hint at least what to look for would be appreciate - having off-band exchanges doesn't help others really.

Hi Oliver In Ali's case, his Collaborator instance was working previously and then stopped working, and he was using the default Collaborator server. Some things we tried to check are the following: - Were there any new updates or changes to the network? - Are there any antivirus software or firewall rules that may be interfering with this? - Are you able to try using a different network to see if that causes any changes? - Could you try disabling all of your extensions, and see if you are able to poll then? Did you follow the documentation on deploying your own Collaborator server? - https://portswigger.net/burp/documentation/collaborator/deploying Have you set up your own configuration file?
