Connection error : Connection reset by peer OS error 104

[clues4me]

Hi, just got twice issue get connected to client. I dont know what its, but i think related to security because its somehow blocked by router/firewall.
The day before its okay, nothing got wrong, but accidently its cant connect to a client, others clients is ok.

Im using debian on both side and installed correctly on x11 desktop.
Rustdesk version 1.1.9

I'm also facing the exact problem.

try this master build

Would you mind doing some explanation before I try that? BTW, I'm on Linux...

This problem has been fixed on master branch. I'll put a linux build on that link later.

Okay, thanks for the fix.

I'm using my Linux machine to setup a server and letting my windows enjoyer friend using mine, for a better direct connection. Does he need to update his client software or do I need to update my Linux server for the fix to work?

Just update client, but can't connect by direct connection. It's solution is changing direct to relay.

Can you try out nightly build? There is a fix, though not good enough, not sure if it works in your scenario.

The nightly build works better, but clicking or using the keyboard causes the os error 104

What env on controlled side?

Same thing here (on debian unstable), with latest nightly .deb and APK.. this comes up in the system log:

Surprisingly, anydesk has the same problem right now when it previously worked. Their hint to

try disabling "Allow direct connections" [or] adding "/np" at the end [of the ID]

helped.. both devices are connected to an OpenWRT router (phone via wifi, desktop via LAN) but haven't changed the configuration for quite a while.. 🤔

[rustdesk]

try disabling "Allow direct connections" [or] adding "/np" at the end [of the ID]

@21pages let's add this also. We have "always use relay" already, for us, it should be try "always use relay".
In addition, add "/np" (let's use "/r" instead) to our id (and set alway use relay for this peer) also.

[rustdesk]

Could you please try out the nightly build? add "/r" suffix to the id. https://github.com/rustdesk/rustdesk/releases/tag/nightly

[eMPee584]

uum, the /r

gives
with latest nightly on desktop / phone.. i can activate "Always connect via relay" in the menu of the connection though which works.
But trying without relay why does it occasionally work well for more than a minute, then keeps bringing up error 104 instantly on reconnect? This is on a local network, what is going wrong.. is my openwrt b0rked 🤔

[rustdesk]

please try out the new fix

[weirdal3333]

It's late, but those patches did indeed fix the error 104 that I was having.
