Failed to connect to MCS endpoint opera

  • Hi!
    What does it mean with:
    Failed to connect to MCS endpoint opera?

    I got a few error messages when I run opera in terminal something like this:

    ERROR:connection_factory_impl.cc(413)] Failed to connect to MCS endpoint with error -102
    [503:503:0804/150845.748391:24554723506:ERROR:networkimpl.cc(528)] [AU] Request sending failed. HTTP return code: 0
    [503:503:0804/150845.798357:24554773471:ERROR:networkimpl.cc(327)] [AU] Send Request status: 60

    My internet is working in opera, I can visit sites.

  • I fixed the error "[503:503:0804/150845.748391:24554723506:ERROR:networkimpl.cc(528)] [AU] Request sending failed. HTTP return code: 0

  • @unknown-user01 You posted all those command lines because.....?

  • @leocg

    ...because I fixed the error with this.

  • @unknown-user01 Which of them fixed the error? Posting all really doesn't help.

  • I don't know exactly, I guess it's one of them: (network part)
