Burp Collaborator Default Servers Showing SSL Issue

David | Last updated: May 19, 2023 08:10AM UTC

Hi folks, When I (and other colleagues) run "Health Check" for Burp Collaborator on v2023.4.3 we are getting a significant amount of errors rendering Default Collaborator not functional. Is this a known issue affecting multiple users? The output of Health check is pasted below: "A TLS error occurred when connecting to the capture server domain using HTTPS. There may be a problem with the certificate. An SMTP connection to the capture server at gauh15039188qzyfdu1p5dkr1i7vle5w9zy.oastify.com port 25 could not be opened. An SMTP connection to the capture server at gauh15039188qzyfdu1p5dkr1i7vle5w9zy.oastify.com port 587 could not be opened. An SMTPS connection to the capture server at gauh15039188qzyfdu1p5dkr1i7vle5w9zy.oastify.com could not be opened. Communication using other protocols did work; possibly a firewall is preventing this connection. The HTTP response of the capture server was not as expected, perhaps this is not a collaborator server. The HTTPS response of the capture server was not as expected, perhaps this is not a collaborator server. No connections to the polling server at polling.oastify.com could be opened. The collaborator will not work in this configuration."
