Protractor Webdriver-manager update SSL error

问题:

I am getting the following errors with webdriver-manager update. My protractor is at version 5.1.1

my_local_windows_directory>webdriver-manager update

events.js:160 throw er; // Unhandled 'error' event ^

Error: write EPROTO 101057795:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:openssl\ssl\s23_clnt.c:794:

at exports._errnoException (util.js:1022:11) at WriteWrap.afterWrite (net.js:801:14)

Any ideas to resolve this issue. I am behind a corporate Lan, but I tried BYOD network as well, but still this did not resolve.

回答1:

1) Restart mac

2) Run this -> webdriver-manager update

3) Run this -> webdriver-manager start

4) Also you can check your ports sudo lsof -iTCP -sTCP:LISTEN -n -P
