PMS Suddenly Not Accessible From Certain Devices

No, not yet.

22

I’ve applied the latest update and rebooted - still having the same issues :frowning: .

@uglymagoo

Can you jump in here? These are your baby.

24

@ChuckPA The issue does not really sound Raspberry Pi specific :confused: It sounds more like a DNS rebinding issue or something like that.

25

I need the full logs at this point.

Settings - Server - Help - Download logs

Please attach the ZIP file here. We’ll start digging.

26

Logs are attached. Thanks in advance.

3.20.8
FIXED:
Fixed issue with dashboard not being visible in recent versions of chrome

Excited to try this once the RPi version is updated! Curious to see if it fixes my Safari problems as well.

Still not working after updating/rebooting. :frowning:

Ok. Time for an extreme step.

  1. Stop PMS
  2. Open a terminal session
  3. sudo mv /var/lib/plexmediaserver/Library /var/lib/plexmediaserver/Library.KEEP
  4. Start PMS
  5. Configure as fresh with a new ‘test’ name to keep plex.tv from being confused. (your previous metadata / library is sitting in the KEEP directory
  6. Test
  7. If the problem is gone, and remains gone, something very deep was corrupted and beyond detecting it. If so, delete the KEEP directory and rename the server back to its original name
  8. If the problem persists, grab a fresh set of log files as soon as you detect it
30

How do I configure fresh once I’ve moved the old data to the keep directory? Once I moved the data it just told me server not found.

31

You start all over just as you did when you first installed…

Open http://ip.of.pms.machine:32400/web in the browser tab . If it’s on your machine http://127.0.0.1:32400/web

Do the full first-run setup

32

That’s what I thought. I do that but don’t get the set-up wizard, it just goes to the dashboard with no content and says no server found on the left side. Is there a way to trigger the set-up to happen?

33

Something triggered the Preferences.xml file to record an ‘owner’

  1. SSH tunnel into the box. (prepare for browser tunneling) ssh -L 8888:127.0.0.1:32400 ip.addr.of.box
  2. when signed in: Stop PMS
  3. delete Preferences.xml again
  4. start PMS
  5. keep the ssh tunnel open
  6. On the local host http://127.0.0.1:8888/web and run setup
34

Got to the initial setup, still same issues though. I’ve attached the latest version of the logs.

Here’s what I see when I try to view in Chrome on iPhone:

I can’t figure this out. I need someone familiar with the Pi.

@uglymagoo can you help out here ?

36

@crawpappy @ChuckPA Still no indication it’s a RPi specific error but I will try :slight_smile: My guess is this is caused by a network problem, probably DNS. So please first reboot your router and afterwards your RPi. Then check that you can reach plex.tv from the RPi, e.g. wget plex.tv. If this is not helping please give us more details about your network and your systems, i.e. Linux OS on your RPi, DNS server configured on your RPi, is there a firewall on your RPi, is there a firewall in your network, do you use VPN plugins or security / privacy browser addons, … . Moreover, can you please check if clients using a wired network connection are able to connect to your plex server and only wireless clients are not?

37

My best guess is DNS rebinding protection in the router/modem, which needs to be disabled. Newer modem/routers are more security aware and, as such, watch for DNS redirection. Some get confused and think xxxxxxx.plex.direct is a DNS rebind (which it isn’t) and fail DNS lookup.

The only way to deal with this is find the setting(s) in the modem/router to turn it off

38

Hey all, thank so much for helping troubleshoot.

If it was a DNS issue, would it only be affecting certain browsers? I can access Plex from inside and outside the local network using Plex apps on Xbox One and PS3, as well as Chrome/Safari on multiple computers. Chrome/Safari on iPhones/iPads is not working inside or outside the local network.

Despite my doubts, I have tried what I could for now (not at home so I can’t mess with router settings.) I can successfully connect to plex.tv from the server via wget. I have the router set to use Google’s DNS servers instead of my ISP’s and I have previously tried reverting back to my ISP’s and this didn’t change anything. The RPi plugs directly into the router, no firewalls anywhere, vanilla browsers on the iPads/iPhones, no VPN. My laptop is wireless and can connect without an issue via Chrome. Here’s the OS version:

cat /etc/*-release
PRETTY_NAME=“Raspbian GNU/Linux 8 (jessie)”
NAME=“Raspbian GNU/Linux”
VERSION_ID=“8”
VERSION=“8 (jessie)”
ID=raspbian
ID_LIKE=debian
uname -r
4.9.35-v7+

@crawpappy Btw: why don’t you use the iOS App? Why Safari? :smiley: I am quite sure the browsers on iOS will not provide a nice Plex experience and I am also quite sure this is not a use case that’s well tested. The web interface is more or less designed for desktop browser (I believe :smiley: ).

@uglymagoo because it’s not free and the iOS browsers were working great for a long time.
