You can gather the Artifactory/Xray logs into a support bundle by going to Admin -> Advanced -> Support Zone. Please create and download the bundle and note the time of the error if possible.
You can then use the following curl command to send the logs to our secure SaaS instance or attach them to the ticket.
curl -i -T filename.ext "https://supportlogs.jfrog.com/logs/<Ticket_Number>/"
Note: You'll need to open a ticket first to get its number, replace "<Ticket_Number>" in the command above with the case's number
