RTSP handshake error 60 after driver update

[cgutman]

A few users have reported RTSP handshake error 60 after updating their drivers. The issue is not affecting the majority of Moonlight users (including myself), but it affects some users very consistently. It must be something specific to their client, host, or streaming settings that is triggering the issue reliably.

Error 60 is ETIMEDOUT which would indicate either a connection timeout or a timeout waiting for a reply from the host. In some cases, GeForce Experience will fail to reply to RTSP messages while waiting for NvStreamer.exe to start. Specific invalid streaming settings (such as resolutions below 256x256) are known to cause NvStreamer.exe to crash, so that may be what's happening here.

Affected users, please provide the following info:

• What was the last driver version to work and the first driver version not to work?
• Do you have "hardware accelerated GPU scheduling" enabled on your host PC?
• Attach your logs from C:\ProgramData\NVIDIA Corporation\NvStream after trying to stream and getting the RTSP error

I am currently experiencing this issue but only over online attempts, not in local network. I am able to connect successfully when at home in my network, but attempts to connect from anywhere else causes me to get this error. I have ensured the ports are open and available through my router / modem.

• I am not sure what driver it worked last on, but currently it is happening on Nvidia Geforce 512.15
• hardware accelerated GPU scheduling is enabled on host PC
• NvStreamerOld.log

Ah, if it happens on remote streaming but not local streaming that definitely points to some issue with port forwarding. I suspect the issue is with UDP port 48000. GeForce Experience will stall the RTSP handshake until it gets a response on that port, so that can lead to timeouts if it's not forwarded properly.

Can you confirm that you have that UDP 48000 forwarded properly?

[mikesells]

I have the same issue as above. My belief is that no forwarding is necessary if I'm using something like ZeroTier correct? I have run moonlight tester and it says all is well.

[cgutman]

That's correct

Same error for me. For more info: Only online. LAN / WLAN works fine. Client = Ipad Pro 11 IpadOS 15.5 M Driver = 516.59 Moonlight Internet Streaming Tester pass correct (attached). Launching the game/app I see client connects with PC and initiate the process correctly,The game/app is launched in the PC but at the same time the client stops returning this error code. The game/app remains working on the PC so I should close it locally.

Thanks

I am experiencing this issue too. Any updates?

[billyjacoby]

I'm having this same issue using a Wireguard VPN that works for a number of other services.

[aur3l14no]

Same, I'm having this same issue using a tailscale.

[cyturralde]

Does anyone have a fix for this?

Same issue: I access my LAN via OpenVPN on my NAS from outside my network and receive the rtsp 60 error when trying to connect to Sunshine on my PC. Also happens when I connect via TailScale directly to the PC. Moonlight client reports no issues when I select the "test network" option and all other remote services are working via the VPN. I've got the port forwarding set up properly on my router, etc. running a 4090 on the 531.79 driver.

If I click on an app via Moonlight while on my VPN, the program starts up (which I can see when I hop on my PC later) but then the 60 error hits.

This used to work fine with GFE in the past (although I couldn't tell you what driver version, unfortunately).

Attaching the log here as well — everything until "CLIENT DISCONNECTED" is me connecting via my laptop on the home network, everything afterwards until [2023:05:21:22:31:59] is me trying to connect from a mobile network and OpenVPN.

EDIT: Think I managed to sort it out by editing my OpenVPN config. Enabled redirect gateway (which is fine for my purposes — might not be for others!) and manually defined the DNS servers.

[thelazurus]

Running into the same issue through Tailscale.

[joshdee]

Same exact issue as well. But I have a router that is capable of self-hosting a VPN through my whole home Wi-Fi, specifically Amplifi Alien. It's a minor issue but I really want to use Tailscale. ^^

[SgtSweetieBelle]

same issue. router port forwarded and everything :(

[ClassyCar]

I've got the same issue. Has anyone found a solution yet? I'm using Zerotier one and trying to connect to my PC from my iPhone.

[adnanjamil-frontend]

Same issue here, any solutions? Connecting with iPhone using Zerotier

[Oolong22]

Anyone found a solution? Using Tailscale to connect from my Iphone. (Sidenote: it seems like a lot of us having problems comes from trying to connect from Iphone. I'll try with my laptop later to see if that's the case)

[boyphongsakorn]

any update? i have a same issue with Tailscale (Mac and Android)
