Private Burp Collab Server Only Failing 'Verify DNS Interaction"

Andrew | Last updated: Mar 15, 2024 02:30PM UTC

Hello, I am running into an issue where all checks are successful aside from DNS Verification. I have confirmed my config multiple times, but am still running into the same issue each time. I am using the server location and specifying the polling location over 9443. Server is hosted in AWS, with appropriate ports open for inbound traffic. See below for output. 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 Success Verify HTTPS interaction Success Verify SMTP interaction Success Verify SMTPS interaction Success Is there something else I should be checking? Thank you.
