Failed to connect to MCS endpoint opera

A Former User

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.

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