Hi, I seem to have a near identical problem to this post from 2019:

I also have 2 NICs but haven't yet tried disabling one in BIOS like OP did.

Completely new Unraid installation. I can ping arbitrary websites when docker is on or off, but with docker on I can't pull images and `docker login` at CLI times out (`docker login` will complete successfully when docker is off).

I've similarly tried disabling bonding, changing bonding mode etc. I have no proxys enabled that I'm aware of. I've tried Google DNS servers (8.8.8.8, 8.8.4.4) as well as my router's original DNS servers to the same effect. The issue persists across restarts.

Appreciate any help, thanks

Don’t know if this is at all related but after reading around in the forums it seems like my NIC (Realtek RTL8111H) could be somewhat problematic? Here’s the mobo I’m using: https://www.amazon.com/gp/aw/d/B0CRB225KX?psc=1&ref=ppx_pop_mob_b_asin_title

 

 I found this plugin for some Realtek drivers: 

 

 

To be clear: I haven’t installed these yet by hand or anything. And I figure if it _were_ a driver issue I wouldn’t have any connection _at all_ whether or not docker was running. Just hoping more context is more helpful to find a fix; kind of grasping at straws here and no idea if this is the right direction. Thanks again

Bump

I'm hoping to get some help on this issue before my trial license runs out in 13 days; otherwise I can't see myself purchasing since everything I want to do will require docker.

Some new observations:
`docker run --network <X> hello-world` will not work for any value of X I've tried, ie `host` or `bridge`. Using `--dns 8.8.8.8` likewise does nothing. It still times out trying to fetch the container.

I've tried `ping`ing from various interfaces and the only one that seems to work is `br0`:

I just tried updating the Realtek R8168\R8111 driver per this linked forum thread. No difference, I still can't `docker login` or `docker run hello-world` when docker is enabled and I can't pull down any docker images through the web UI.

I have 2 days left in my trial license and I will not be able to buy unless I can get docker working.
