Hi there - I’m Abe from the Product team. I’m not able to reproduce this issue, but would happy to take a look if you’re still experiencing this behavior. Would you mind opening a support ticket and then sharing the ticket number here shortly after? We’ll likely need a .har file and the Tunnel ID you observed this behavior for if you’re comfortable sharing this information through the support portal.
I just had the same issue under the same circumstances. I was adding a new hostname and suddenly all of the other were gone and inaccessible. The DNS entries remain however.
Not sure if relevant but I was adding the new hostname from a mobile browser.
Did you happen to find any solution other than adding them all again manually?
