Describe the bug

When trying to run a server transfer, Laravel complains of null argument given to the processFailedTransfer() call:

[2021-05-06 21:22:20] production.ERROR: Pterodactyl\Http\Controllers\Api\Remote\Servers\ServerTransferController::processFailedTransfer(): Argument #1 ($transfer) must be of type Pterodactyl\Models\ServerTransfer, null given

This is also not well transpired to the nodes (transferer and transferee) which they only see a 500 coming from the panel.

A clear and concise description of what the bug is.

To Reproduce

1. Have 2 working nodes, where you are sure you can spawn new servers and have available allocations.
2. Go to one of the servers.
3. Click on Manage
4. Click on Transfer Server
5. Select the other node and one of the available allocations
6. Click Confirm
7. Check the logs of Laravel in the Panel and Wings

Expected behavior

Transfer process should be initiated with no issues as it used to be.

[notAreYouScared]

I'm not able to reproduce this, Might be an issue related to the docker'd version of wings and the panel?

I was able to move a Minecraft server between two nodes, A->B B->A, without any issues.

[elmorti]

It is quite possible, my infra setup is a bit more complex since I am running the nodes on a containerized virtual machine (QEMU under Podman for the VMs that are running CentOS for Wings and Docker) so at the beginning I was suspecting of some networking issue but since the Laravel log was complaining about ServerTransferController::processFailedTransfer(): Argument #1 ($transfer) must be of type Pterodactyl\Models\ServerTransfer, null given I thought that somehow the code logic is unable to get the right node/server information to pass to the function, thus getting a null reference. I might need to setup a proper CNI to make this work but I'll check also why the null reference is happening, maybe something can be arranged in the code to actually support the setup. Both nodes are reachable between them by proper DNS resolving so I believe that, thought my setup is not the most common, it could be supported. I'll try to do my part of research though :) (I have zero experience with PHP and Laravel beyond configuration of apps)

[elmorti]

I think I am gonna close this issue and double check whether my particular network infra is not causing any problem.

Little late to the part here. I had the EXACT same issue, but my error was a 404, not a 500.
ERROR: [Jan 18 19:45:16.536] panel returned an error when notifying it of a successful archive status error=Error response from Panel: DaemonConnectionException: An error occurred on the remote host: There was an error while communicating with the machine running this server. This error has been logged, please try again. (code: 404) (request_id: bd8a2753-7a7b-4512-a6b9-11fae8704354). (request id: bd8a2753-7a7b-4512-a6b9-11fae8704354) (HTTP/404) server=df49dc7a-b3e0-4c8a-a5be-648562b47aeb

I updated the panel and wings and the transfer worked. The fact that it gave a 404 is still confusing, though.
