Hint for HELP

Spent hours on this box, and I can’t even get the credentials through the high port. Please PM with any help

EDIT: Finally managed to get user and root. Thanks to @JGruloos @ghost0437 and @CyprusDonkey for the help.

Only managed to get through the unauth way. Would appreciate a PM on the credentials part though. At least just how to the endpoint on the XXXX port
