Cannot start agent a second time with containers.

The first time I ran the agent with a container it worked correctly and went through the motions. I uploaded to PlayFab but it said my build was unhealthy, so I went back to try it again. Now this shows up:

info: MockPlayFabVmAgent[0]
Event: ContainerStats. Properties: NULL, Metrics: {"containerCreationTimeMs":101.0}
info: MockPlayFabVmAgent[0]
Created a container with session host id: d21d16cca1a0a886c41473ef4466d7e18fc29faf0d409814ea8cacc4770767b9

I made sure to run the two commands at the end of the guide to end all containers.

hey @asusralis, which guide did you follow? As mentioned here, the LocalMultiPlayerAgent is meant to be used for local development, not to be uploaded onto PlayFab service (unless I misunderstood something).

So, I tested the game on my computer and it worked. I then uploaded the build (what was tested on my computer, NOT the agent) to PlayFab and it did not work. I then went back to my computer to test it again to see if I could figure out why it was working on my computer but not on the PlayFab server and I wasn't able to get the agent to run again. I did not upload the agent to PlayFab.

That is the guide I used. I was able to run my game in a container and it went through the motions. I tried it again the next day and it gave me those errors.

Maybe Docker networks on your local installation have an issue? You might want to restart the Docker daemon. Maybe try deleting docker networks and retrying (here's the CLI reference -> https://docs.docker.com/engine/reference/commandline/network/). Sometimes deleting the "DockerNAT" virtual switch from Hyper-V Manager helps, you can restart Docker from system tray to recreate.
After that, you can run setup.ps1 to re-create the networks.

I had the exact same issue, running setup.ps1 again fixed that

Thanks for reporting that @starburst997!
