"ERR_CONNECTION_TIMED_OUT" with Vivaldi

Pathduck

@datacenter In addition to doing the above troubleshooting, it's important to note that a TCP RST will immediately reset the connection. It should not lead to a connection timed out.

For instance it's a common way for anti-virus or security software to hard terminate a connection to sites it's registered as harmful.

@DoctorG

Hey there,

Thanks and below are the details:

Windows Version - Windows 10, 21H1
Vivaldi Version- 4.0.2312.38 (Stable channel) (64-bit)
Windows Firewall - tested it with on/off - no difference
I have no AV at the moment
Only one extension - AdblockPlus, tried without it too

Vivaldi is working, but regularly I get ERR_CONNECTION_TIMED_OUT and after a F5 refresh it manages to open the website.
The issue is not happening in Firefox, meaning this excludes most of the stuff like router, lan, etc.

@datacenter Try to reproduce the problem and capture only the traffic between your host (assuming .40) and the host that times out (assuming .69).

Also try to use the F12 Devtools Network tab and note what you see.

Try to use basic network troubleshooting tools like netcat or telnet to port 443 and see if you get the same result.

And even if you say "no extensions" - try in a clean profile.

Apologies for the delayed response, I have tried a lot of things and did additional captures with wireshark and I have retransmits on random when using Vivaldi.
To be honest I have tried everything possible, although the most important finding for me is that the problem does not manifest when using Firefox.

I have tried:

factory reset on the router (btw, not using WiFi)
my connection seems great (no packets loss, no flaps, I game online a lot)
reinstalled my network drivers (Intel Ethernet Controller I211 Series)
reinstalled Vivaldi
tried Vivaldi in a portable version
tried Vivaldi in mint condition (e.g. no extension, no profile attached)
tried different DNS providers like 8.8.8.8, 1.1.1.1, etc.
tries firewall off/on - no effect
called my ISP, they say they do not see any issues on their side.

I have used chrome network log to capture the activity on the browser level, here it is (cannot attach files in this forum, so I have used external provider with 30 days retention):
https://easyupload.io/bmmeq6
-- the problematic website was -> www.ces-schools.net

I have followed the instruction from here:

Any help will be appreciated

@datacenter Thanks for the log and for trying different things on your side.

It would be easier if you just captured a HAR file, it's much easier to understand.

~~Far as I can tell, there's no mention of any network timeout in that log.~~

Is it only this site that gets these errors?

It looks like the site is hosted on Google servers - are you running some kind of software that would block connections to Google servers?

@datacenter In addition to a HAR file like said above, it might help to capture a log with WireShark and share it. But use a capture filter, like host www.ces-schools.net to avoid too much irrelevant data.

Since HTTPS traffic will be encrypted anyway it shouldn't be a problem sharing the data from WireShark.

But for the HAR file - if you are logged in to the site, make sure to log out and clear data before recreating the issue and saving the log, as it will contain potentially sensitive data like cookies.

Edit: Also, have you tested in other Chromium-based browsers, Opera, Brave or even Chromium itself? What about in Chrome?

@Pathduck

Hey there,

Thank you again for your time!

No, nothing blocking google services, actually use them a lot (like google search, youtube). This is happening on random sites and once the websites opens, the issue does not appear anymore for that particular website (at least for the day).

I have made a video, so you can see first hand how it looks and exported the HAR file, again this is a random site:

Video: https://easyupload.io/gjbese (VirusTotal - just in case)
Har File: https://easyupload.io/65blm5 (VirusTotal - just in case)

Pathduck

@datacenter OK I had a quick look. The HAR file is from a working connection, so it's not much use. But thinking about it, a HAR file would be little use anyway when the connection closes or times out as you just get the standard error page.

A tip: When doing your testing, a good idea is to always use a clean, standalone profile. I notice in the video you're using ABP so that would kind of be the first suspect - even if you've said you earlier tried with it disabled. Keep a Standalone install of Vivaldi around for testing stuff like this. Whenever you want to "start fresh" you can just delete the User Data folder without having to worry about deleting your regular profile in your standard install.

The video shows the issue, but it's not a timeout, it's ERR_CONNECTION_CLOSED. But it does take a bit of time, which is strange, a connection closed would usually be instant.

It has to be something either on your system or most likely your ISP, it's the only idea I have. But it works in other browsers, something I can't explain.

Did you test in other Chromium-based browsers?

Doing a tasklist /svc in cmd and sharing it could be useful seeing what processes you have running, might be something you've overlooked.

A capture from WireShark might help as well - when you have the time

@datacenter

this is a great article and it resolved this issue on at the first step:
https://www.softwaretestinghelp.com/err-connection-timed-out-error/

ok, so i got this error by tethering my android through t mobile

i read somewhere that vivaldi is incompatible with android. i don't know the details. i tried a vpn called proton, which has a free version

immediately, i was able to log into my vivaldi account, and sync my browser (reinstalled my o.s. - win 7)

i didn't read anywhere that you were using tethering or maybe you're using android, idk. i don't know how to use a vpn on an android. i used proton on my pc, and was able to connect to vivaldi.net through my android

@hmazuji

p.s. it's kinda ridiculous not being able to use the forums because of a glitch like this. how can we post the problem when the problem is preventing us from posting ? like, duh
lol

anyway, i did generate the suggested har log if someone here wants to see it:
how do i upload the har file
i should have taken a screen shot

@hmazuji Coyp the log file and post it with </> code button.
