I am currently unable to access Community Applications. Whenever I attempt to do so, I receive the following error message:

"Download of app feed failed. Community Applications requires your server to have Internet access."

I have tried configuring several public DNS servers, including 8.8.8.8, 9.9.9.9, and 1.1.1.1, and have also rebooted the server multiple times but it doesn't resolve the issue. I am not using pi-hole or anything.

At this point I am out of ideas, I am unsure of how long this has been occurring I don't login to the dashboard very often.

Attached are my diagnostics.

Server doesn't have internet connectivity; as a first step, rename/delete /config/network.cfg on the flash drive to revert to default DHCP and post new diagnostics.

I have renamed the /config/network.cfg and the /config/network-rules.cfg to network.old and network-rules.old and I am still having the same issue. The server is on DHCP, and I open a terminal from the webui I am able to ping ca.unraid.net, github, and get responses back.

This system does have two NICS in it and for troubleshooting purposes I have tried both ports.

The more and more I troubleshoot this the issue seems to be with curl itself, I can wget the same URL and it resolves just fine

There's still no internet, try booting with a different flash drive, no key needed, see if you can install CA, this is to rulke out a config issue.

I will more than happy to do this to try and rule out a bad config but can you help me understand what you are seeing or what I am overlooking to conclude there is no Internet.

Every other Internet terminal based command ping, traceroute, wget works. Even curl works by ip if I recall

In the diags, system folder, there's a plugins.txt file that lists all the installed plugins, and this first line there, means Unraid is unable to reach the internet.

Could not download current plugin versions

New Flash Drive made running 7.3.1 and the same issue occurs.

I have been looking at this in detail with the OP.

wget can resolve DNS names, curl cannot, dig cannot - by default.

curl within docker can resolve DNS names.

Comparing PCAPs of these various DNS requests, the failing requests include the OPT record, while the successful requests do not. The failing requests are being dropped somewhere, presumably due to being too large.

Using dig with the "+noedns" option allows it to query DNS names successfully.

When the DNS server is set to default, meaning OP's router, the same behavior happens, so we think the router is likely the failure point. Unfortunately, the router is little more than a black box from the internet provider, so fixing the problem there does not appear to be an option.

Presumably the reason that some OS components are doing this is due to a setting somewhere for DNSSEC, but we are not finding anything like that.

How can one cause the various components that are making DNS requests with the OPT record, such as curl and dig, to instead make DNS requests without the OPT record?

That basically confirms to me there's an external issue with your LAN/internet.
