Ip Address changed and now Apps do not work

[Dr. C]

I am a novice in the server world, so this may be a simple fix. I searched the forum but did not find any current information on the issue.

I had an internet issue, and the tech guy messed with my Static IP that ran my Server. I reset the static IP address, and all is fine for TrueNAS, but the apps are not working; more importantly, I use File Browser, and I cannot access my files because the app uses the old IP address.

When I access the SHELL of the File Browser app, this is the message I get: Error from server: error dialing backend: x509: certificate is valid for (OLD IP address) not for (NEW IP address)

Any help or guidance would be most appreciated.

So, I ran into this issue with plex breaking after I changed the TrueNAS server's IP. The fix was to go to Apps > Settings > Advanced Settings, and update the Route v4 Interface and Route v4 Gateway settings.
