[ReenigneArcher]

If the service is running, you shouldn't run sunshine manually

[GustafXTT]

Pardon me if I didn't make it clear, the service was not running before I manually executed Sunshine.

A sunshinesvc.exe is running in the background, which contains a Sunshine Service.
A sunshine.exe keeps trying to start and fails every 3 seconds in the background.

It means the situation after I tried to run Sunshine.

[ReenigneArcher]

Something is using a port that Sunshine needs, maybe you have multiple instances running?

I would just restart your computer.

[GustafXTT]

A reboot didn't fix the problem.

[GustafXTT]

Just did some tests and found no process using port 47990, maybe it's not a port conflict issue.

[ReenigneArcher]

The logs indicate something else is using a different port.

[GustafXTT]

The information after this log, which I provided a translation before:

An attempt was made to access a socket in a way that the access permissions do not allow.

Could it be a permission issue?
If not then I have no idea :(

[ReenigneArcher]

Could it be a permission issue?

Yes, I think there are also other permission issues.

Running Sunshine as a service should prevent permission issues like this though, since it runs as the SYSTEM account.

[GustafXTT]

Trying to solve the permission issue:
Give both sunshinesvc.exe and sunshine.exe administration permission was not working.
Reinstalling an old 0.20.0 version / latest beta version of Sunshine was not working either.
Manually running the exe file & Starting the SunshineService from the task manager's services panel were working neither.

[jvvilar]

Adding that I'm experiencing the same issue. Sunshine service is running and the application keeps trying to start. I have already searched for anything using the 48010 port and found nothing. (Both netstat -ano | findstr :48010 as well as Get-Process -Id (Get-NetTCPConnection -LocalPort 48010).OwningProcess)

My log ends slightly differently though:

I encountered the same problem. My computer has Hyper-V enabled.

[LouKordos]

Same issue here, I also get

[Lapis256]

I also encountered the same issue.

After executing netstat -ano | findstr "48010", I found no processes using the port, so a port conflict is unlikely to be the cause.

However, I confirmed that specifying an arbitrary port, such as port = 50000 in sunshine.conf, resolves the issue.

Additionally, the problem seemed to occur after installing KB5050094, so it might be related.

[GustafXTT]

However, I confirmed that specifying an arbitrary port, such as port = 50000 in sunshine.conf, resolves the issue.

It does fix the problem for now, thanks.

Additionally, the problem seemed to occur after installing KB5050094, so it might be related.

I reckon the problem can occur before KB5050094 since I have not installed it yet.

[Smarter-Mind]

Because the SW is retires every 3 Seconds, the old Socket may not be clear yet.
Most likely you need to set ENET_SOCKOPT_REUSEADDR, so it can re-use the socket

So it will look something like;

  //Set Sockopt reuseaddr, so if the SW does a retry,  it can reuse the socket address
   if (enet_socket_set_option(host->socket, ENET_SOCKOPT_REUSEADDR, 1) < 0)
    {
        std::cerr << "Failed to set socket option for address reuse.\n";
        enet_host_destroy(host);
        return 1;
    }
