steamwebhelper, a critical Steam component, is not responding. The Steam UI will not be usable.

I've had this error pop up 2 days ago and I haven't been able to fix it. I'm running Windows 11 and after one of the latest updates I haven't been able to run steam. I've tried everything I've read, here's a list of what I've tried (some of which I can remember as of now):
- Uninstall the last windows update
- Delete steamwebhelper from C:\Program Files (x86)\Steam\bin\cef\cef.win7 and cef.win7x
- Run compatibility mode for Windws 8, disable fullscreen optimizations and running the program as an administrator
- Deleted my achievments folder
- Deleted usardata folder, and config folder inside of it
- Add it to my antivirus program whitelist, turned off antivirus, turned off firewall
- Disabled GPU acceleration
- Deleted Steam completely from the Program Files (x86) folder AND from the Users folder, and reinstall it from a fresh setup.exe
- Deleted Steam completely and reinstall it in Program Files instead of Program Files (x86)

At this point I don't know what else can I do, I have gone through tons of videos, reddit posts, Steam forum threads, etc., and I still can't open it, if anybody knows something I haven't tried or has had the same problem as me and solved it I'd be so happy to hear you.

Thanks for the reply man, I actually solved it yesterday. I read on some random post that someone disabled TCP BBR2 and that worked for him, I don't even know that that is, and he didn't specify how he did it so I asked copilot (lol) and disabled it and it worked!

Look we dont know why you have TCP issue at your connection, ask own ISP if you need to do so. if you dont get the diffrence in TCP and UDP packet's and both is needed in a modern connection and both do jobs that other has as Pro's and Con's, it's better to say unless you have been told to do do so by local ISP then you should not do this.

No one in Right mind today make one protocol over the other, because no mater how you explan it its like ying and yang they need each other. ( you need a screwed up network issue, that need to brake standard ways, because traffic is a issue. )

So technicaly you can what you are doing is wrong. and your conclusion is also wrong unless as i said your ISP have told you to do so. ( this is not even debatable then you know what TCP is doing and UDP protocoll is doing. )

And be happy i and other bother with a reply, more make sure this is the case so you dont make more traffic issue with games. ( any network technician can tell you this. or you need to read network book about it. atleast.)

gl with it, if this is what you think this is right, you also forget this can effect other service in top of this.

[Iceira]

And as always if youi have any network issue contact own ISP = Internet service provider, no one else has support on the area. ( problem is what service do they actual have or want to help ppl with . )

Standard pc user is 1 router with DHCP and gateway with DNS server and in NAT.
this could be seen as most frequent connection solution in the world.

Also why i post this then you do not follow standard, if we can call it that here.

And NO you do not use a Free DNS server, ( you only do that for test then ISP own DNS server has a issue. ) if you do not know inherit DNS Tree, and why it is so, we can't all be on same DNS server, it's that simple.

Most here know this, but there is so many steam user that do not do this or have this..

Hey man, I must say English is not my first language. With that being said, I'm sorry man but I really didn't understand a thing of what you said lol, I don't know what any of that means idk any of those terms, I just looked up a solution, tried it and it worked for me, I don't know what it does, if it's good of bad for my internet (?) or anything.

[Iceira]

This is why Ask own ISP is the right way. they should know this, any network people can tell you , you dont normaly do that , say no to TCP connection that now run though UDP packets that normal a no GO unless as i tried to tell you they have emergency fix or that build you live in has a issue with it.
its so rare this is the case, but who knows.

i mean i only know africa shoolcase where upd was NO so its traffic run in TCP, so traffic get to its destination, and that 30-40 years ago, even africa has fiber today, so as you see things can have consequence then you fiddle with TCP and UDP prtotocoll, today its seen AS never do so unless order by own ISP as best suggestion, for the moment.

this is your connection, and it rasie more question why this work for you, and yes we could sy we dont care, but fact is TCP connection to game server is a most UDP packets here have consequence.

Dont forget other steam user also read this, and what if they think its a good idea, its here gamers dont need bad connections with UDP Solutions you will be dropped in packets that is what UDP do. ( has actual nothing to do with it work for you ) it was what the protocol are ment to do. drop UDP packets if something goes wrong.

you need to understasnd what a broadcast packets is. ( ISP supporter should know this )
be lucky if a steam moderator see your post, and know this, problem here you dont need to understand network for be a steam moderator.

Required Ports for Steam
The following are ports you need to have open on your router or firewall for Steam to operate normally.


To log into Steam and download content:
HTTP (TCP remote port 80) and HTTPS (443)
UDP remote port 27015-27050
TCP remote port 27015-27050

Steam Client
UDP remote port 27000-27100: Game traffic
UDP local port 27031-27036: Remote Play
TCP local port 27036: Remote Play
UDP remote port 4380

Dedicated or Listen Servers
TCP local port 27015 (default): SRCDS Rcon port
UDP local port 27015 (default): gameplay traffic

Steamworks P2P Networking and Steam Voice Chat
UDP remote port 3478
UDP remote port 4379
UDP remote port 4380
UDP remote ports: 27014-27030

As you see here steam TCP traffic is there for a reason, and so are the games devs ports. for game server.

Man, I cannot thank you enough for posting your solution. I had this problem crop up a couple weeks ago and had been through all you had and much more. I had enabled BBR probably 6+ months ago (on purpose, to deal with high latency throughput applications I deal with) and would have never thought this to be the issue.

Flat out, this has to be a built-in and purposeful incompatibility with the Steam client and it's the only time I've ever encountered any issue with BBR vs. cubic. BBR is far superior to cubic in practically all throughput applications, I'm surprised Steam isn't natively supporting it.

I'm happy my post was able to help you! I should mention that I still have absolutely no idea what BBR is, LMAO.

I am here as obviously have this atrocious problem and I have already spent 6 hours trying everything, while I got excited for a few mins looking at thsi thread then it subsided...
I couldn't make head or tail of it and then when you mentioned ports and the like it simply is to complex for me.
I'm a games fanatic and the only way I can play on my new pc is to play in Compatibility Mode which is not ideal as I'm getting poorer performance including some stuttering.
Please some one try and help me?

Hey there, I understand, and I too have absolutely no idea what TCP BBR2 is or anything like that, so here´s what you can do:
If you have copilot installed in your PC (AI program) (if you don't have it you can use chatGPT instead), open it and type in the following prompt "how can i turn off TCP BBR2 in my pc? step by step", it should tell you how to do it, just follow the steps and you should be good.

Hey do you remember or can you please find the post that mentioned this?

[LOLA BLiTZ3R]

if you are having STEAMWEBHELPER is not responding issue, I tried every other fix and this workaround is the only thing that worked.

What i do is

Open Task Manager, click the Performance tab, and select Open Resource Monitor to display the Resource Monitor.

If you cant find resource monitor there you can search for it in your search bar, you need to use resource monitor

In Resource Monitor, keep the "CPU" tab open, and in Task Manager, keep the "Details" tab open. (edited)

Start Steam, once steam webhelper appears in your processes right-click Steam.exe in the process column of the Resource Monitor and select "Suspend Process." This will allow you to ignore the Steam webhelper waiting timer and wait for a long time. After that, wait until the memory usage of steamwebhelper.exe in Task Manager stops increasing (about 1 to 2 minutes in the author's environment). Then, in resource manager you can click on Steam.exe and resume the process and steam will launch.

YOU HAVE TO WAIT FOR STEAM WEBHELPER TO APPEAR in the processes before suspending steam

THIS FIX WAS FOUND BY SOMEONE ELSE, I am just reposting to create awareness

Steamwebhelper is a component that is launched by Steam itself when Steam starts. It looks like Chromium is running inside.
Steam waits for several tens of seconds for this webhelper to finish launching completely, and then starts the main body after confirming that the webhelper has started.

Looking at the startup log, it looked like the error was occurring because webhelper was starting up normally, but it was taking longer than Steam expected to start up.
So, to solve the problem, it looked like we needed to either get webhelper to start up faster, or get Steam to wait longer.

Thank you so much! I was tinkering with TCP in order to fix long connection times. Haven't rebooted my laptop after that for some time, so would've never guessed that was the issue. Your post saved me a lot of time!
