Ah, I think I see what you mean. Nautilus (gvfs actually) is temporarily downgrading the protocol for the discovery, but it's not reverting that when trying to actually connect to a discovered host. Is that it?
This does ring a bell, it was supposed to be fixed with an SRU on bionic, and in the development release back then. That SRU is what enabled this temporary fallback to smbv1 while doing discovery, and reverted when connecting. This needs troubleshooting. ** Also affects: gvfs (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1881780 Title: Nautilus requires SMBv1 to work from "Other Locations" without manually typing in the address.
