Two days ago, OBS experienced network instability.

Hi, I've been having a problem with OBS for the past two days. It's extremely unstable, to the point that I can't stream in any quality. At first, I thought it was due to a vertical streaming plugin, but it turned out that was the problem. I've tried many configurations, downloaded network testing programs, changed cable positions, reset the cable, and even spoken with my internet provider. Everything points to a Discord issue, which is funny because my brother also streams, and most of the time he streams at the same time as me, giving him a total of three simultaneous streams (if I'm dual streaming). He was also streaming on Discord at the same time, and nothing happened. The only option I haven't tried is reverting to a previous version of OBS. I've posted the OBS crash report above.

Have you tested using OBS Studio in Portable mode with absolutely NO plugins, filters, or effects applied? and certainly not multi-streaming via plugin per recent threads ... ymmv
And what are you doing for real-time network monitoring? and this is all ethernet/wired, no Wi-Fi involved, right?

The crash relates to a browser source, it seems. No specific network instability. How did you mentioned it?
Try to identify the browser source and disable (or delete) it, to see if that helps.

Your crash report says that a thread of one of your browser sources crashed primarily. From this point on nobody may tell u, which browser source it is.

You have to go thru your scenes (or at least know, which scene was active that very moment) and tell by yourself, which browser source may have been crashed.

Hint: Make an backup of your profile AND your scene collection. Then drop browser sources one by one until no crash happens for hours then. Maybe you guess which browser source possibly demands too much from the browser plugin.

I didn't have any active browser sources, and I've reinstalled several versions of OBS, but the problem persists. I finally called the company, and they came to look at the router. I explained the whole "little problem," and now I'm running tests, but the problem continues. I really don't know what to do. Maybe the problem is with the company itself, but they explained that it's not their fault.
It's a real headache.

If you don't have browser sources then it could be a browser dock. Your crash report mentions libcef.dll which is the Chromium Embedded Framework library.

I replaced the libcef.dll file in System32. I also had the option to format the PC, but I chose to replace it. I'm leaving logs because it seems to have stabilized my network somewhat, but every 2-5 minutes the bitrate drops drastically and then stabilizes again in a few seconds. All the options in the Network section of OBS were disabled, and there was one instance where the bitrate was showing in red, but it remained at the stable bitrate for about 2 minutes.
I still find this situation quite strange.

Are you sure?

When I went to place the file, it said "Are you sure you want to replace...", but in that case, should I delete it?

Okay, I deleted the file, made sure there were no problems, and now it's not changing or stabilizing.

I'm leaving the network settings as they are.

I did another test with the "Dynamic Bitrate" option, and the last time before calling the technicians, it wouldn't hold. Now, at least it looks like a "normal" live stream. Now, the quality only drops when a lot of things happen abruptly on screen. It's an improvement (I think).

Update: This is weird.
I wanted to continue streaming with the dynamic bitrate option since it was working better. The bitrate was still showing in the red most of the time, but the stream looked good in both landscape and portrait modes. After a while, I started noticing that the bitrate was staying in the green, so I stopped the stream, disabled all the Network options in the advanced settings, and the bitrate was stable throughout the entire stream. Also, in this setting, the IP address wasn't set to default, so I changed it back to default. My problem now is that the log shows 51% dropped frames, even though I didn't see that in the statistics. This worries me, since this is the latest log, and I'm afraid it might have been mixed up with a previous one. As a final note, I'm streaming at 1 AM. I doubt it's due to the time of day, but I'll have to talk to the company again to see if they can figure out why this is happening.

Hey everyone, today, unexpectedly, the internet company technicians came to check on everything, but mainly to verify the internet speed. I took the opportunity to do a live stream test to show them the problem, which they found very strange. They confirmed that there was no packet loss on the Google and YouTube servers, and indeed there was. They checked with the central office, and after a few minutes, they confirmed that the connections were stable. They checked the OBS logs and didn't find anything unusual or any program that was actually interfering.

What they found even stranger was that despite the poor performance, the live stream didn't suddenly close. There were times before when it showed 100kbps internet speed and the stream didn't drop.

But aside from that, they were going to investigate thoroughly, and if they found the cause of the problem, they were going to call me.

Selecciona la Familia IP a IPv4 solamente.
Desmarca las optimizaciones de red y control de ritmo TCP.
Prueba a ver si con esto ya funciona bien.

Si el problema sigue, posiblemente sea por una mala configuración en la empresa de internet sobre el protocolo RTMP. Los técnicos no verifican esto a menos que se les diga. Y esto suele ser un problema de configuración en algún router o servidor de la empresa, que no toman en cuenta este protocolo.

Por otro lado, no deberías usar la captura de pantalla junto con capturas de juego y/o ventana. Interfiere con estas.
Las capturas de pantalla deben ir en su escena por separado.

El navegador Opera no es un juego, no deberías usar la captura de juego con este. En todo caso utiliza una captura de ventana o, en una escena separada, captura de pantalla.
Se recomienda usar la aceleración por hardware para los navegadores y para las fuentes de navegador. En especial con la placa de video que posees.

I would suggest leaving Dynamic Bitrate on. At one point your bitrate went to 1000 in your log, but low quality frames are better than no frames. I believe it can go as low as 50. Try streaming with HEVC or AV1 because they get more quality per bit compared to H.264. In the Output settings, you can also try changing Multipass Mode to Full Resolution and B-Frame as Reference "Middle b-frame only" for H.264 and HEVC and Each for AV1. Both of those use additional GPU for more quality per bit so you may need to adjust your game graphic settings (side note: just purchased V for PS4. Currently at 45% install).

Be aware that Display and Game Capture Sources interfere with each other. You really should never put them in the same scene (Escena 2).

Muy bien estuve haciendo pruebas, esta de aqui fue a las 9 PM, con todas las opciones de red activas con la opcion de bitrate dinamico activo.


La segunda cambie las configuraciones a HECV con "Full Resolución" , "Calidad media" , aunque ya tenia el presentimiento que no era el problema, no perdia nada en intentarlo.



Y ahora la ultima Seleccione solo la Familia IPv4, Desmarque todo, y fue peor de lo que espere, este lo hice a la 9 PM.

Ahora porque nombro el tema de la hora, anoche cosa de la 2 AM hice un directo, porque en uno de los registros mas estables que tuve fue a esa hora, el directo de anoche no tuvo ningún problema, aparte de que no se guardo en los registros, pero fue estable al punto que desactive todas las configuraciones y subí el bitrate a 14000kbs, estable.
no se porque será.
Hablando por ultimo del opera siempre lo ocupe antes, incluso con brave y microsoft edge abierto y nunca presento algun problema, pero, no porque, la aceleración de hardware no se activa, lo revise en los 3 navegadores y no marca en el analizador de OBS como activado, y por si fuera poco nunca lo tuve desactivado.

Ahora, sobre el protocolo RTMP, al servicio al cliente le digo que si los técnicos podrían revisar la configuración de empresa sobre mi internet o pido directamente a los técnicos que vengan (por tercera vez) a revisar el router
