SMB connection issue after June update

j.davids · 5 June 2020 03:11

Wish I could, Putty closed itself before I could

fzinken · 5 June 2020 03:14

Ok, I guess maybe armv7-connman-osmc was removed.
If you want to try to get it going without a reinstall you should be able to do so via the terminal started from the Vero (Choose Exit and press ESC)

fzinken · 5 June 2020 03:15

And my apologize openvpn might have come in as a standard service recently.

j.davids · 5 June 2020 03:20

It’s unable to to resolve ftp.debian.org & apt.osmc.tv
Reinstall it is.

fzinken · 5 June 2020 03:21

Well as mentioned if you are eager to save the install could bring the files in via USB stick.
But if you have a recent backup then reinstall should be as fast as.

Hello,

Same situation on my side. After the June update, playback is working for a few seconds then stops (Kodi on Vero 4K accessing a NAS over ethernet connection).

How can I downgrade firmware to previous version? I have a backup from yesterday of my settings

fzinken · 5 June 2020 06:52

Please provide logs so that we can check if it identical issue.

Downgrade not easily possible, fastest way is to reinstall and replay your backup. But first upload logs, if it is the same issue then we should be able to investigate for a fast official solution.

Same issue here since the june update : https://paste.osmc.tv/vusiwipeqe

Setup is a vero 4K with a synology DS218j NAS on a gigabit switch.

Does this only happen with some files?

stevanazzi · 5 June 2020 13:13

Yes, I’m currently looking for a pattern

sam_nazarko · 5 June 2020 14:19

Which version of SMB are you using on your NAS? I seem to recall this problem only affecting SMBv2.

I know what’s causing this issue and can push a fix, but it then breaks WMA playback. So I want to get a bit more information before making any changes.

stevanazzi · 5 June 2020 15:30

The NAS is configured to support both SMB v1 and v2.
Kodi is using v2 according to a tcpdump trace.
Two files from the same show (same codecs) are behaving differently.

Here the end of the tshark trace :

sam_nazarko · 5 June 2020 15:32

Does your NAS support SMBv3?
Can we get a trace of that?

JimKnopf · 5 June 2020 16:10

Hi @stevanazzi and @j.davids ,

could you check whether you specify the smb versions on Vero and Syno like shown below?

Eternal_Pessimist · 5 June 2020 16:45

Running NFS fine on Synology DS416J. The xxx16j has SMB3 so try switching both to SMB if you dont use NFS. NFS is faster.

stevanazzi · 5 June 2020 17:24

Hi, with v3, it works fine. Thanks for the tip.

j.davids · 6 June 2020 04:08

Now that I can finally respond again, the solution by JimKnopf worked wonderfully.

Thanks to everyone who tried to help.

JimKnopf · 6 June 2020 04:36

@stevanazzi, @j.davids: Could you tell what DSM version is running on your Synology NAS? You find that data at the Synology’s Control Panel->Info Center->General.

Here it’s a small DS214se with DSM 6.2.3-25426.

sam_nazarko · 6 June 2020 04:45

I’m hoping to fix the issue for SMBv2 users tomorrow.

j.davids · 6 June 2020 04:53

No clue what DSM version I was running before as I updated while troubleshooting but I am currently running 6.2.3-25426
