Here is my web log

44

While debug logging was enabled, were you able to recreate the failure?

It doesn’t look like you have from what was attached. Specifically,

    "type": "info",
    "host": "app.plex.tv",
    "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36",
    "browser": {
      "platformVersion": "10",
.
.
.

        "isBundled": false,
        "isFallback": false,
        "relay": false,

It’s not using the Plex/Web loaded from the Synology.

Tried again. Reinstalled Server, accessed URL from inside my Syno.
Literally have no idea what I’m doing at this point.

46

Forgot an important step.

Sign out of Plex/Web (upper right corner)
Open incognito window
Open http://ip.addr.of.syno:32400/web

As FYI, Server code doesn’t impact what we’re seeing except for the change in bundled app version.

47

Signed out.
Incognito.
Open http://ip.addr.of.syno:32400/web
Enabled Debug.

Mine is working right now. Changed nothing…

Also an update of Server Logs

I am seeing DNS rebinding protection as active in your logs now. I was looking for this.

In the modem/router, do you have the ability to grant exceptions? (I don’t want to disable it)

If you do, please grant exception for plex.direct private domain. It will greatly speed up the LAN clients and server interaction. Nothing will have to go out to plex.tv and come back.

There is still a plex.tv connectivity issue.

It’s sluggish at best. Which region are you in (i have forgotten) ?

51

Texas

52

I added manual DNS Entry for plex.direct

53

Having lived in the D/FW metro, I know Texas is its own country :wink:
but we’ll have to find out why central CONUS isn’t responding.

There are Plex folks in Austin.

54

I have questions into the web app team now.
Trying to find out what was changed in client-server interaction because this is too profound a departure from norm.

55

Thanks for the update, and thanks for your help.
Going to provide back story in case it might be helpful.

Back Story:
Established Synology NAS with Plex for 4+ years.
I upgraded ISP service virtually at the exact same time as the outage on 02/06/20.
Old Router/Modem: Coaxial WAN. >>> New Router: Ethernet WAN.
I use Google Wifi sytem as my main LAN interface. I wanted to dump the router and go straight to Google Wifi.
I removed the router and added a Netgear Unmanaged switch.
ISP > Google Wifi > Netgear Switch > Synology NAS > Plex Media Server
Never got Plex working.
Apparently, unmanaged switches don’t handle DCHP servers!?
I switched everything BACK to Frontier (ISP) Router and added port forward.
Uninstalled/reinstalled plex server about 6-10 times.
At one point I was able to access plex from my phone but NOT the web?!?!
Deleted Plex server from devices on web app, expecting it to refresh/reappear.

Thats about all I can think of.
Thanks again.

56

If I may make a few corrections?

  1. WiFi is what’s wrong with the picture. – Most WiFi units will create a second subnet unless you expressly set it as same subnet with the LAN. PMS on WiFi is asking for trouble. It’s OK for clients but never the server.
  2. Unmanaged switches do nothing more than pass packets, including broadcast and DHCP packets.

Now, what has changed? Where is the DHCP server?

57

Any thoughts on my log issue?

58

Current setup (since joining this thread):

ISP > Frontier Router > Synology > PMS

@slushy

Can you grab the logs as they stand now, without purging any of the older logs.
(total log usage for all logs is only 64MB)

I was unable to access my Plex Server on my NAS as well. Reinstalling Plex and restarting appears to have fixed it for me.

61

So I did what you wrote yesterday.

  1. Plex/web browser - Upper right corner - Sign out of your Plex account.
  2. Restart Plex on the Syno
  3. Wait the typical 30-45 seconds for it to get settled with Plex.tv
  4. Open an Incognito browser window
  5. Connect to http://LAN.IP.of.syno:32400/web
  6. Sign-in
  7. Claim again if needed but should auto reclaim.

Result is the same, problem remains. At my Samsung TV I only get a view with circles behind my mapnames. Although there seems to be some progress, because I could watch a movie. But at the other hand I couldn’t open the menu to see the remaining movie time, the buttons to play fast forward and other things.

I use version 1.18.5.2309. I uploaded a log file, don’t know if this is the right file, because this is 3.1 MB and the others I see were only a few kB :woozy_face:

Sure, here they are. I installed an older version to see if I would have better success. UnfortunatelyLogs.zip (197.6 KB) , I have not.
