Hi Chris,

I finally (!) take the time to reply to your email.
Very sorry for this very late reply.

Actually, I already contacted support sites before raising a bug:
https://askubuntu.com/questions/1489891/my-ubuntu-22-04-keeps-running-smb1-protocol

And here is what I was replied:

*In Files ( Nautilus ) go to Connect to Server and ask for the server AND
it's share explicitly. For example:*

*smb://192.168.1.22/Photos <http://192.168.1.22/Photos>
*

*The problem is a design flaw in gvfsd-smb-browse. Even though SMBv1 is
disabled in samba itself it still allows a force setting to that dialect
which gvfs uses to "discover" ( browse ) available hosts on the network.*

*The gvfs developers think that is the only way to discover hosts on the
network. This isn't true but it is what it is.*
I'm not skilled enough to evaluate if this is relevant but from a user
perspective, I randomly failed to access my NAS through GNOME files because
gvfsd actually used SMB1 protocol.

*And when I run "journalctl -f" on my Acer and then try to connect to the
NAS, here is what I get:oct. 09 21:56:32 xxx gvfsd[9205]:
smbXcli_negprot_smb1_done: No compatible protocol selected by server.*

Today, I tried again, and it worked!
I don't know if something has eventually been modified in gvfsd.

I hope it gives you more context to my bug report.
Let me know if I missed something.

Best regards.

Title:
  Can't connect my Synology NAS from Ubuntu 22.04

Status in gvfs package in Ubuntu:
  New

Bug description:
  I purchased a Synology DS723+ NAS (under DSM 7.2-64570).
  I access it without any problem from a Huawei MateBook 14s running Ubuntu 22.04.

  I can't do it, however, from an Acer Swift 5 also running Ubuntu 22.04.
  Seen from this PC, I get the following message:
  "Unable to access location
  Failed to get list of shares from server: Invalid argument."

  When I look at my NAS log, the connection attempt gives the following message:
  "Host [192.168.1.22] failed to connect via [SMB] due to [SMB1 not permitted]."

  While the message obtained after a successful connection with the other PC is the following:
  "User [xxx] from [xxx(192.168.1.36)] via [CIFS(SMB3)] accessed shared folder [Photos]."

  I tried to compare the differences between the 2 PCs running Ubuntu 22.04 without success.
  Samba was not initially installed on the Acer Swift 5 initially, but the installation did not correct the problem.
  After reading different posts, I understand that the SMB1 connection is disabled by default since Ubuntu 20.04: I therefore do not understand why the Acer Swift 5 seems to connect like that.

  And when I run "journalctl -f" on my Acer and then try to connect to the NAS, here is what I get:
  oct. 09 21:56:32 xxx gvfsd[9205]: smbXcli_negprot_smb1_done: No compatible protocol selected by server.
  oct. 09 21:56:47 xxx gvfsd[9205]: smbXcli_negprot_smb1_done: No compatible protocol selected by server.
