El Capitan Synology

Hey,

additon on my post where i meant that restart is a solution, after i restart the syno the file server was available in the finder, but not connectable constantly.

So following steps does fix the Problem constantly.

1. turn smb off on the syno (at my syno it was off, because no windows at my network)

2. restart syno

3. first turn off smb and afp -> and then turn off file sharing on the Mac

4. restart the mac

If i do this on a MacBookPro, IMac and a MacMini everthing works normal like before on Mavericks, also Time Maschine.

@ B_Volkovyski did you try to deselect your Time Maschine Volume in (System Preferences -> Time Maschine) and select it again (maybe with a Mac restart between)?

sorry forgot the step Nr. 5

5. turn on file sharing and specially afp on the mac system preferences

I've tried only deselect and select Time Maschine Volume without restart.

Thanx for advice I will try it and post the result.

None of the suggested solutions worked for me. Server is still losing its connection after some minutes.

I can temporarily fix it by unplugging the ethernet cable or deactivating network connections and activate them again.

But these solutions suck though.

Apple provide a fast solution please!

I think this has been sorted. I just got a new 27" imac and it connects to my Synology Cubestation perfectly.

It was (hope so) finally fixed in 10.11.2

All previous recommendations has a temporary effect and doesn't solve the problem.

Obviously it was a problem in Finder or Network sharing layer.

Shame on you, Apple! You was my last hope in the world of unstable computers and operating systems 😟

This is still an issue as of yesterday (12/16/15) with my rMBP running 10.11.2 and my Synology DS213. After attempting multiple fixes (WINS settings, SMB and AFP settings, network settings, etc...) from several posts both on here and the Synology pages, my fix was simply resetting my Airport Extreme.

The second it reset the NAS showed back up in my finder. Hopefully this will help someone else that's still in the same situation 🙂 I feel slightly dumb for not doing a router reset at first haha...live and learn I guess. Apple seriously needs to address this issue since the problem is so wide-spread.

I am having the same issue, DSM 5.2 update2 and 10.11.2.

I see the shared folder under Select Backup Disk. But does not connect .

I have a very similar problem. I get the same error message ("There was a problem connecting..." ) for an SMB share on a raspberry pi that worked great on Yosemite (and earlier) but now fails after an El Capitan update.

When I try to "Connect As..." I don't get prompted for credentials, and I don't see saved credentials in my Keychain.

Any ideas?

Any way to reset/clear the saved credentials used to access my SMB shares?

I get this message 'The operation can’t be completed because the original item for “DS1515” can’t be found.' Specifically, I see my DiskStation as a shared volume in a finder window. And it shows the shares: music, video, surveillance, and the main share I named DS1515. The finder window shows "Connected as: admin". But when I click into the share DS1515, the window disappears and the finder reports 'The operation can’t be completed because the original item for “DS1515” can’t be found.'

Strangely, the shares for 'music' and 'video' don't make the window vanish and seem to work. Also strangely, uTorrent can open a working view of the DS1515 share. But accessing it directly from the Finder fails as described above.

Clearly, El Crapitan is to blame for all this. I had upgraded to the latest Synology version earlier. All the trouble started after the El Crap update. Amazing that Apple could take a protocol that has been working for a decade or more, screw it up out of the blue for no good reason, and already be at 10.11.2 and not care to fix it. At this rate, Apple stock will fall below $100...

I'm still having the same issues as well. I have tried everything BUT resetting my AirPort Express because that would mean setting up all of my network ports all over again and I don't really want to do that.

I started having the issue when I was on the 10.11.3 beta so I downgraded but it didn't fix anything. I still have the same problem. I'm beginning to think that it may very well may be the router and not the computers having the issues but I don't see how that could be possible personally.

When I tried resetting the file sharing by turning off SMP and AFP, rebooting, and then reconnecting my Raspberry Pi (using Netatalk) actually connected for like 2 seconds and then it disconnected and I started getting the same issues again.

I honestly don't know what to do, I get this exact same issue with my Mac Mini that is running my OS X Server with TimeMachine, so none of my devices are getting any backups. It's causing me to waste a lot of time testing when I should be doing. Apple really needs to fix this problem.

Rebooting my U-Verse router did not solve the problem for me.

DiskStationn shows up in my Shared area and works just fine. Just can't time machine backup

10.11.3 came out today. Does it fix the problems?

(I'm out of town away from my Synology and can't test)

No, it doesn't change anything, it's still the same problem.

Same issue basically here. I was the only person to upgrade to El Capitan at work, and after a week I have lost my ability to connect either by SMB or AFP to the NAS. I believe my previous Yosemite cache was still connecting until it was flushed, now there's nothing.

We have limited access to the media server other than restarting it, which was done with no good results.

I am connected via a direct wired connection to the media via a switch, which is operating fine upon testing as the others are connecting well with Yosemite.

Something changed in El Capitan, and Apple needs to somehow revert to the Yosemite code with this connection issue.
