I see there's an error about tty command not found?
17:14:46.759569 tramp-wait-for-regexp (6) #

I think that's from tramp-open-connection-setup-interactive-shell, this
part particularly:
;; Set `remote-tty' process property.
(let ((tty (tramp-send-command-and-read vec "echo \\\"`tty`\\\"" 'noerror)))
(unless (string-empty-p tty)
(process-put proc 'remote-tty tty)
(tramp-set-connection-property proc "remote-tty" tty)))
Here is another relevant log output for connecting to alpine:
