No auto reconnect after NSPOSIXErrorDomain error 9 - Bad file descriptor

[yang (Yang.Y)]

This is a really frustrating issue. Could you please enable DEBUG3 log level and post desensitized
full log while Core Tunnel failed to reconnect automatically?

Enable logging

The default logging level is set to Info, Debug1, Debug2 and Debug3 each specify higher levels of verbose output. [image] Core Shell Open or go to Hosts tab, right click on the host and select Edit Settings… from context menu, navigate to Connection tab, then scroll down to Log Level option. Press ⌘ I (or select Shell -> Show Inspector from main menu) reveals shell session information, as well as log content. [image] Core Tunnel Navigate to tunnel's Settings…, Connection tab, then scrol…

BTW, is there any crash reports (with process name io.coressh.openssh) in Console.app?

Kindly Regards,
