That account appears too be a member of the admin group, as you say. I will go back over your instructions and see what happens. I have noticed an odd thing, in that if I am unable to play a movie with the Amazon Fire Plex app (which is usually the case, especially early in the day), I close it and start up the Panasonic Plex app where I can play the file fine. If I then return to the Amazon Fire version,I _am_ now able to play the movie. ![Screenshot 2025-09-07 at 09.17.37](https://global.discourse-cdn.com/plex/original/4X/0/d/f/0df51c14f87dda3c16093efc89d12e96659daec5.jpeg) ---

I’ve been going over my settings afresh, but I have run into an unexpected issue, responding to your message entitled ‘NAS Settings’ above. In Synology Control Panel → Network → Network Interface I only have LAN (Connected) and PPPoE (Disconnected), I don’t have Network Address, Subnet Mask, Gateway or DNS Server. I wanted to try and get this sorted before I do anything else. Anyway, the NAS is indeed synchronised with a public server ([time.google.com](http://time.google.com)) ---

If the NAS is synchronized to a NTP server, then the network connection is almost always OK. I ask people to do that because (a) it is a good thing for NAS operations, and (b) it is a basic check of Internet connectivity. To display/edit the address, etc. edit the connected network interface. Example: My Synology NAS I’ve a simple network, only one router, no VLANs, etc. The gateway is the address of the ISP supplied router. ![syno network](https://global.discourse-cdn.com/plex/original/4X/9/b/f/9bf26f2eb33000d9e9034892c6b29061da648f01.jpeg) ---

Additionally, today I have had an ‘At Risk’ warning generated by DSM\>Security Advisor (see screenshots). I have no idea what all that means TBH. Is it something to be concerned over? It’s quite alarming. ![Screenshot 2025-09-10 at 15.09.37](https://global.discourse-cdn.com/plex/original/4X/a/5/9/a592c851a44483f70c43a577820c159ab400929c.png) ![Screenshot 2025-09-10 at 15.09.47](https://global.discourse-cdn.com/plex/original/4X/2/b/7/2b7acc251992c8bec56db74872f55013074017b1.png) ---

Mystifyingly, my media is now accessible again, although only on 2 devices/Smart TV’s. So the issues continue, seemingly without end. [FordGuy61](https://forums.plex.tv/u/fordguy61), I am going to try and finally complete DBRepair this week. ---

If you study the image you posted carefully, you may notice at the bottom it lists the issue that caused the alert. Go to _DSM Control Panel \> Terminal & SNMP_ and change the default SSH port number (22), to another 2 digit number E.G. 23. And remember that when logging in via SSH you will need to add _-p 23_ to the end of your log in command in terminal/PuTTy. E.G. ssh [myadmin@192.168.0.22](mailto:myadmin@192.168.0.22) -p 23. In this case, -p = the port number you chose above. Also, I would recommend that you reboot your modem/router and everything connected to it, including any wireless devices. That should clear any DNS Cache corruption that may be contributing to your issues. ---

Marvellous 🙂 I changed the default SSH port number to 24 (23 was being used by something) and managed to log in (I think) - well the cursor is green now, quite a relief I must say. I’ve attached a screenshot in celebration. Given that my original aim was to run DBRepair, do we think that it’s achievable from where I’ve got to? Thank you for all your support. ![Screenshot 2025-09-11 at 15.41.08](https://global.discourse-cdn.com/plex/original/4X/8/e/7/8e735b4c93fdfece4cc27ba29b549b48ee805b67.png) ---

Absolutely, it’s possible. I would save Chuck’s DBRepair script somewhere in volume1 (accessible from File Station), but NOT in the PlexMediaServer folder. CD to it’s location and chmod -x etc. to make the script executable and then run the script as per Chuck’s instructions. That should clean up your database and make sure it’s running as well as it can. ---

All my media has become invisible to Plex (“NAS is currently unavailable” - it’s not). It was fine yesterday. Nonetheless, I will try and give DBRepair a go. I have relocated the file to a different part of my NAS, as you suggested. My biggest challenge is how to CD too it’s new location (easy with a graphical interface of course…) Do you think that DBRepair will iron out some of these problems? I would dearly love to be able to watch my stuff once again. ---

Sounds like you have a network issue that you may need to address. Try rebooting the modem/router and everything connected to it and then restart Plex and try opening Plex/Web using [http://NAS-IP-ADDRESS:32400](http://NAS-IP-ADDRESS:32400). At the SSH prompt enter: cd /address/to/the/file > E.G. > cd /volume1/Files/ (changing directory to) > chmod +x DBRepair.sh (making the file executable) > ./DBRepair.sh (running the file) Make sure you replace the file address with the actual file address on your system and do not include the text in parenthesis above. ---

+x tells chmod to set the executable bit for the file, DBRepair.sh in this case. The command to use is: `chmod +x DBRepair.sh` You want to add the executable bit, not remove it with -x. HTH ---
