Failed to open TCP connection RSpec + Capybara testing (Ruby on Rails)

[SaidRasinlic]

Hola every1,

I've been struggling a lot recently to fix this issue. I really Googled a lot and couldn't find an answer, most of the related questions were left unanswered.

Issue description:

I'm trying to simply test my cases with RSpec + Capybara with Selenium by running the command rails test:system (even rspec spec outputs the same), but for some reason the Google tab which opens is blank, and I also get a TCP connection error printed out. I was trying to find where this issue came from but couldn't.

Error images:

Version details:

• OS: Windows 10
• Ruby version: 3.1.2
• Running a command "rails webdrivers:chromedriver:version" prints: 2023-04-13 12:11:12 INFO Webdrivers chromedriver 112.0.5615.49

What I've tried so far:

I tried to change the timeout from 60 seconds to above by overriding Capybara timeout variable, but it didn't work! I really don't know how to fix this, it's been a while since I've been stuck on this, and I can't find an answer anywhere. If someone knows what's going on here please let me know.

Thanks in advance 🙌

Did you figure out what to do? I'm having a similar issue

Yes I did!

Solution: As you can see in the screenshot, line 61 should be commented out and please make sure you add a break statement after it, the file location of socket.rb on my PC is C:\Ruby31-x64\lib\ruby\3.1.0\socket.rb. I think it's their bug that somehow passed unnoticed in their sockets, and I was too lazy to send them a pull request, so if you want, guys, please do it. I hope this fixes a problem for you as well as the others.

Please comment below if this worked for you so I can close this and mark it as resolved!

P.S: My eyes bled trying to solve this error back then 🤬
