April 11, 20251 yr I recently started noticing an issue with one of my Docker apps, specifically Plex was giving me issues that only occur when it doesn't have an internet connection (e.g. not able to scan new library files, not getting metadata for new items, etc.). I was troubleshooting that particular app and got to the point where I decided to just remove and reinstall the container. Unfortunately now I am getting an issue with the Apps page at http://<serverIP>/Apps which is inhibiting me from moving forward. Community Applications requires your server to have internet access. The most common cause of this failure is a failure to resolve DNS addresses. You can try and reset your modem and router to fix this issue, or set static DNS addresses (Settings - Network Settings) of 208.67.222.222 and 208.67.220.220 and try again. Alternatively, there is also a chance that the server handling the application feed is temporarily down. See also this post for more information Last JSON error Recorded: Syntax error I have tried updating my DNS settings to 1.1.1.1, 8.8.8.8, and 208.67.222.222 with full system reboots between just to make sure it isn't my adguard DNS server muddying things up. Also verified DHCP and other such settings. Nothing glaringly obvious as I haven't changed anything with IP assignments. To my knowledge, nothing in my network settings, firmware, or anything has changed aside from my updating that particular Plex docker app from the list of Docer apps (http://<serverIP>/Docker) a couple of days ago, thus why I wanted to downgrade it but am now seeing this issue with the Community Applications page. The application's logs are showing entries like this: Apr 11, 2025 10:05:11.496 [22406386404152] WARN - [HttpClient/HCl#f3] HTTP error requesting GET https://plex.tv/updater/products/5/check.xml?build=linux-x86_64&channel=16&distribution=debian&version=1.41.6.9685-d301f511a (6, Couldn't resolve host name) (Could not resolve host: plex.tv) Looks to me like a DNS issue since it cannot resolve a URL, but I can't seem to figure out what setting needs to change to get everything back online. EDIT: I also just tried to manually download the update to 7.0.1 from 7.0.0 and got a network error from the installer: plugin: installing: unRAIDServer.plg Executing hook script: pre_plugin_checks plugin: downloading: unRAIDServer.plg ... plugin: unRAIDServer.plg download failure: Network failure Executing hook script: post_plugin_checks plexus-diagnostics-20250411-0948.zip Edited April 11, 20251 yr by Gyakusetsu Added additional info
April 11, 20251 yr Community Expert Solution Remove the gateway from eth1 and eth2, typically, only eth0 should have a gateway set.
April 11, 20251 yr Author @JorgeB I have gone ahead and removed the gateway IP address from both of those interfaces and rebooted the system. Unfortunately that has not resulted in any change in behavior.
April 11, 20251 yr Author OHHH ok, dang, I guess that was still on there. I removed it, rebooted and yep, that seems to have solved all my issues. If you don't mind explaining, I don't remember changing this setting anytime recently so I am unsure why this suddenly would have caused issues?
April 12, 20251 yr Community Expert If you have multiple gateways, they need to have different metrics, or it will be a problem, 7.1 adds some guardrails to avoid this, though not sure how it was working before with that config, AFAIK it shouldn't.
