Server Version#: 1.25.1.5286
Player Version#: 4.66.1
I recently (1 week) got this amazing NAS. but i can not remote access plex with out using the relay option.
Ive tried port forwarding on both router and nas, enable various https options on the nas (there wasnt many), im resorting to trying to create a ssl certificate but its proving difficult and i want to cry.
is it the pms firmmare at fault here? is there something on the nas i need to accept secure connections?
anyone please help me.
To make PMS work on Synology –
Do not overthink it 
(it’s easy to on Synology)
You don’t need a certificate. Plex provides what’s needed.
The modem/router (there should be only one – the ISP one) will provide the port forwarding
Confirm please - in the Plex/Web browser
– Settings - Server - Remote Access
– Everything set to Automagic 
Check the Synology firewall .
– If it’s enabled, Manually create a rule to Open TCP port 32400
– Most of us run with it off because we’re already protected by the modem/router’s firewall.
If this still doesn’t allow the Remote Access to turn green (check mark),
– Restart Plex
– Wait 2 minutes
– Download the logs (settings - server - troubleshooting - download logs)
– Attach the ZIP file here so I can look at it.
Thank you for the prompt response sir.
in remote access in PMS it set to automatic (not selected manually specify port) I haver also removed any port filtering/forwarding rules off the router)
firewall on the router (stock from ISP) is enabled with ip flood detection enabled only.
the Synology firewall is off
logs attached.

thanks for pinging again. (forum must be 
… I didn’t get notified)
What device is trying to connect which gets that message ?
all. my mobile iOS devices when on 4g. my brother on Plex lg remotely from outside the country.
could you not see anything in the logs?
also on the pms it say connected remotley then a minute access out side local network is down.
its as if there’s something on then as preventing secure/https connections outside of port 5001 (DSM https)
I didn’t see any remotes in your logs.
With respect to DSM’s desktop port 5001, I cannot help you there. DSM desktop security changed a lot with DSM 7. Synology has become very strict with the port.
Only you should be accessing the port from your web browser for the purpose of administering DSM.
You should not be using it to open Plex. Plex’s apps can open your server by themselves through Remote Access.
Regarding the LG.
If the TV falls into one on this list then it’s a known failure on the TV’s part
There is a way to allow his TV to work (unsecure) while keeping other devices secure.
ok he does have an older one, about 2 years old. so this maybe a consideration for his connection. adding the IP for him will be ok. but I can’t and don’t want to add everyones ip manually
also what what about iOS. that still supports secure connections, so why can’t we get a secure remote connection from my my PMS on the NAS?
it isn’t isolated to one type of device. even via web browsers remotely, I can not get a remote connection with out using the relay.
when you say you couldn’t see any remote connections, do you mean you could see anyone trying to connect remotely?
regardless of the tv issue, I still got a remote connection to any device. not even port forwarding works, which always usually does when I have this issue in the past does!
I’m starting to think this nas was not the best purchase for Plex
With the TV issue identified - potential solution in hand.
Which version of iOS ?
The same problem is true (expired certificate) if iOS hasn’t been updated.
There is also an iOS version minimum limit.
As a test, change your connection settings from Required to Preferred in both the server and the app.
See if they now connect.
The server logs will tell us more about what’s happening.
I tried this and if if I change disable or required, I loss connection to the sever remotely all together.
iOS is up to date.
you have to understand that I recently had my sever, in the uk on a windows machine with none of these issues up and and till last week. connected. I now migrated to The Netherlands and since upgrading to this has I’m running in to problems.
ive tried installing pms only mack book and coming into the same problems.
I want to think it could be an isp issue?!?!?
updated logs

His IP address stays the same. We add his ip to Plex in the network setting and he still couldn’t connect via the web browser
If you give him your IP and he cannot connect directly via the web browser ?
You have a port forwarding problem.
If you can’t connect manually, Plex never will.
Please go to your modem/router, sign into it, see if the WAN IP it reports matches what you get from whatsmyip.org
I’m becoming suspicious of the ISP
I see my isp is ivp6 and I also see this is the potentially the issue. so an ssl cert is needed to get by this (I think I was right before)
he can not access remote by using my IP address.
by adding his IP address to my Plex, as allow without authentication, he still couldn’t access it.
all paths lead to ivp6
You are both IPv6 only ?
Just me as far as I know.
He is not because I can remote access the server at this location.
