Server Version#: Player Version#:1.41.7.9823-59f304c16 Hello, I’m newbie, french and an old man, so apologize for my english. Since 5 june, I encountered problems on my PLEX installed on a QNAP NAS TS-453D. All worked fine on Philips Google TV, Fire TV stick, … and now PMS seems unreacheable. I tried to update from 1.30… to 1.41…, rename Preferences.xml, uninstall/reinstall PMS, delete all authorized entries and server entry too, use the ./claimpms.sh. ![image](https://global.discourse-cdn.com/plex/original/4X/0/8/5/08579851cc26a87e23556b0d0c8038ac15437101.png) But impossible to reclaim the server. Strangely I have now something strange when I try to download PMS. ![image](https://global.discourse-cdn.com/plex/original/4X/d/4/4/d4473fcd2130b2922a29d21743fe8b45f669cf63.jpeg) I really appreciate if someone can help me. ---

Your server is having difficulty communicating with plex.tv servers, which is necessary to claim the server. Try configuring the QNAP to use a public DNS server such as 1.1.1.1 (Cloudflare), 9.9.9.9 (Quad9) or 8.8.8.8 / 8.8.4.4 (Google). You may also need to change the DNS settings on your PC. You should be able to download PMS and generate a claim code at [https://account.plex.tv/en/claim](https://account.plex.tv/en/claim). Plex’s status page does not show any outages: [https://status.plex.tv/](https://status.plex.tv/). However, there could still be a local or regional problem causing difficulty reaching Plex hosts. > [@147CBServer](#): > > uninstall/reinstall PMS On QNAP NAS, when you uninstall PMS it also removes the [Plex Data Folder](https://support.plex.tv/articles/202915258-where-is-the-plex-media-server-data-directory-located/). This will remove any existing library definitions, server settings, etc. Just be aware of it for future updates, etc., so you do not have to completely re-create your server. > [@147CBServer](#): > > use the ./claimpms.sh. Also: [User Credential Reset](https://github.com/ChuckPa/UserCredentialReset) utility. ---

Thank you FordGuy61. I changed DNS to cloudflare for both NAS and PC. It’s Ok now for downloading QNAP version again. ![image](https://global.discourse-cdn.com/plex/original/4X/2/8/9/2894fa360c1033819d10bcb671843dc2ab58dbb8.png) I use User Credential Utility, but got : ERROR: Could not get credentials from plex.tv (Error: 60) ![image](https://global.discourse-cdn.com/plex/original/4X/5/f/6/5f618efe628addc37053f2255ec26c27494c54e3.png) ---

Do you have a proxy? Something is getting in the way. Trying to figure out what. Edit: One other thing to check is the SSL certificate on the QNAP. See if it needs updating. ---

No proxy but double nat because I use an ASUS router behind BOX provider. How can I check SSL certificate on QNAP ? Seems that troubleshooting starts with NAS firmware upgrade. I don’t use PLEX every day ---

Your system looks OK (DNS works, certificate is valid). This may be something specific to QNAP and the latest firmware update. I’m checking with someone more familiar with QNAP NAS. ---
