Sonos app on wifi cannot see Plex server

Ah sorry to hear those suggestions didn’t work. It does sound though like the App ‘Plex’ connection is hindered by some kind of power management in your case and the connection is timing out on first launch. 

I left my NAS all evening, having watched the England/Serbia Euro game, that started at 8pm and went and opened Plex in the App around midnight-ish and it opened without issue. So I’m not sure it’s the App.

However, that said, in my own case, the NAS/Plex server here uses a dual gigabit teamed (round robin) network connection, so it’s a pretty fast link. So maybe it’s a case the Plex service in the Sonos App needs to wait a little longer for some server connections to respond.

I have run old 16.1 app on my iPhone. The Plex service works really well there.
One thing I failed to mention is that on the old 16.1 app I can also select ”Other Sources” and can then access one of my friends music library on his Plex server which he allows me remote access to.
If I try this on the new IOS app on my iPad it says “Something went wrong, try again”. Trying again never works, it just repeats the message.
So perhaps when I initially load Plex on the new app it is also trying to populate the “Other Sources” details and timing out. That may be a difference between yours and my setup?

@Ken_Griffiths ,
Great that you have such a fast network. Mine is only a single 1gigabit connection.
My NAS is also only a DS224+ and no SSD drives installed.
I tend to agree that the new app is probably timing out too early.
Thanks for your help/suggestions.
Ross.

Your nas and network are plenty fast. Try ruling

out your hard drives hibernating causing the time out:

Control Panel > Hardware & Power> HDD Hibernation, and select none from the first drop-down menu.

@Bumper 
Thanks for the suggestion , as per @Ken_Griffiths suggestion above I turned off Hibernation as per your suggestion above and re-ran my test and unfortunately it made no difference.
FYI: Ther Sonos Plex service always ok via SonoPad app, old Sonos 16.1 app and new Sonos web app. It only times out using new IOS app.

Sorry I missed that, I should have known Ken would cover that as he’s very thorough.

An update on my Plex timeout issue just in case it helps anyone else…

In an attempt to speed up the Plex response to Sonos I ticked-off nearly all of the Plex music library “Recommended” setting within Plex below. All of them were previously ticked. 
When I now select the Plex service within the new Sonos app it now (nearly always) responds with data as expected.

Just FYI: The only area where Plex still fails is when I go into “Other Sources” within the Plex response to Sonos where it fails with “Unable to load content” in the Sonos web app and “Something Went Wrong. Try Again” in the new Sonos IOS app. I am not concerned with this error though.

If Sonos are following this thread, I request that you increase your timeout value when you are waiting for a response from Plex.

My Plex latency issue has appeared off and on again over the last week or so. I have been speaking to Sonos about this and just FYI here is their latest comments…

Since the launch of the new Sonos app, we’ve seen customers in Australia, New Zealand and other parts of the APAC region having latency or delay while navigating the app. This behaviour you’ve encountered while navigating Plex in the Sonos app seems to be related to this issue and we’d like to let you know that we are actively investigating this and do not have an ETA to share.

Assuming you guys are not in the Asia Pacific area that would probably explain why it is working fine for you. The Sonos IOS app is sometimes quite laggy (but useable) for me even outside of the Plex service, which would also be explained by the above comments from Sonos.

Ross.

The odd bit here is you mentioned that the Service on Sonos only struggled when you went into the “Other Sources” area which in my case shows my two NAS Plex servers and if I select one, or the other, it selects that server for display in the usual way to browse that chosen server. That normally takes place locally, or so I thought as it uses NAT loopback on the router to then access the local Plex server. I’m just not sure therefore why it would vary by region. When I get a second, I will post some photos of my ‘other sources’ area just to make sure we’re referring to the same place in the Sonos Plex display.

Just to add something further too @rosswells127, the two GNU Linux, simple mirrored raid-1 NAS boxes here, although now ‘old’ (and perhaps due for replacement) were customised/upgraded by myself long ago and they do have additional RAM - I put in a total of at least 8GB in each NAS if I remember correctly. They also each use ‘teamed’ gigabit (dual Ethernet) adapters in ‘round robin’ mode, so they are fairly fast, even by modern day standards for a NAS box, so that too might be a reason if there is some sort of time-out affecting the Sonos Plex service. So there could be some mileage in that too, ‘perhaps’, depending on the spec. capabilities of the NAS you have - maybe if there is a ‘time-out’ in play here, perhaps Sonos (or Plex) may need to adjust things slightly… still not sure though why it might only affect some regions, we shall have to see🤔?
