Error on protractor: "Timed out waiting for the WebDriver server at http://127.0.0.1:50636/hub" executing on firefox - protractor

Question

I was executing my scripts on firefox and got one notification for Firefox upgrade which I closed. Started execution again but I'm getting error as below,

Kindly help me with solution to this issue.

Answer 1

You have to do the following to make it work:
upgrade protractor to the latest, currently 3.3.0, version which would also bring selenium-webdriver 2.53
downgrade firefox to version 46 and don't let it update for a while (there are compatibility issues)

Answer 2

In my case it was the local firewall (iptables on Linux) that was very restrictive such that WebDriver could not contact the Selenium server hub at whatever TCP port.
To make it work I turned off the firewall. The long term solution was to adjust the firewall rules such that this type of connection is allowed.
If you want your scripts communicate directly with the Firefox|Chrome Driver (bypassing the Selenium server entirely) then try adding the directConnect: true in your protractor.conf.js

Answer 3

I solved it by change the browser (use Chrome instead of Firefox).
In C:__projectWorkspace__\src\test\javascript\protractor.conf.js
modify the entry
capabilities: {
'browserName': 'firefox',
to
capabilities: {
'browserName': 'chrome',
That wasn't enough. I had to change also the webBrowserDriver 'cause after the JHipster installation the 2.22 version was written in protractor.conf.js file but in the path:
node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_2.25.exe
the chromedriver was 2.25 version so i edited the entry
webbrowserDriver = prefix + 'node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_2.25.exe';
and it worked!

Answer 4

I solved this by restarting the computer.
I don't know why, but I think that "suspending" the computer can cause some bad configuration with Selenium Server.
Ah, I run commands on the command prompt as an administrator.

Answer 5

I fixed this issue by changing directConnect to true in base.config.js from repository folder.
or
webdriver-manager clean and then webdriver-manager start
