Moonlight returns Handshake fail on android 5

[masakk1]

Describe the bug

Hello, I got an android 5.0.2 tablet.

Issue

I installed Moonlight, and it was able to see my pc "fedora-pc". When I try to pair one another, once I input the PIN on the host, the client will just return "handshake error".

Disclaimer

For reference, I got Moonlight working on my Android 13 phone (Redmi Note 10 Pro) with no issues, even over internet instead of LAN. I even got my WiiU to work with this moonlight/sunshine setup.

My guess and problem with this

I am very confused. If it were because I was using an old version of, then it makes sense. But I'm using the latest and greatest. I could even get it from the play store....

Steps to reproduce

1. Install Moonlight (APK from GitHub, or from the Google Play Store)
2. Computer shows up
3. Send request to pair
4. On host PC, add PIN
5. Moonlight immediately returns error "Handshake Fail"
6. Sometimes after a couple of seconds another error shows up "Unexpected end of steam on Connection { many numbers }"
7. Pull your hair for days

No response

Relevant log output

Client (Moonlight):
- Handshake error
- unexpected end of stream on Connection{host.ip.x.x:47989, proxy=DIRECT@hostAddress=/host.ip.x.x:47989 cipherSuite=none protocol=http/1.1}

Host (Linux, Sunshine):
No logs when trying to connect or disconnect

Additional context

The issue persist when using both Windows and Linux as hosts. Those hosts work with other moonlight clients.

Also on the section "other moonlight clients" why isn't there an option that says "None"?

I suspect it is related to TLS cipher negotiation. Your Fedora system probably requires ciphers that are newer than what Android 5 has. You can try adjusting your settings in /etc/crypto-policies/back-ends/opensslcnf.config to loosen the restrictions until you can successfully connect.

Thanks for you time @cgutman , I am a little confused on how I can loosen the restrictions for the ciphers. I was able to adjust settings, but I'm unsure what setting and what value to put exactly.

On the file I can see there is a variable called "TLS.MinProtocol", I tried lowering the version to TLSv1.1 instead of v1.1, but I really don't know what I should put in here. Also, is it possible to only loosen the restriction for sunshine? I wouldn't want to be exposed.

Also, the same "Handshake Failed" error persist on Windows, do you know of a way to fix it for that OS? It will be my main gaming system.
