Fedora 25 64 bit workstation - Some sites can be accessed, some cannot
If you run the page https://slack.com/help/test in your browser only the Web Socket connections fail. The issue occurs even when running Fedora 25 from live usb stick. I'm using DSL wired connection - I've tried everything (disabling firewalld, changing all values in the network settings, currently IPV6 is ignored) but couldn't find explanation as to why sometimes (even quite often) the Web Socket connections fail - https://slack.com/help/test Never had similar issue before with prev Fedora or Windows. Any help?
I see web socket success, it might be your ISP blocking things, try using vpn or proxy
It's not the ISP, it works fine with the same wired connection under windows. I connect to the ISP via DSL using username and password so not really sure how i could try vpn or proxy. It must be a config thing with the DSL but what. I used to use Fedora 18 with the same wired connection and never had this issue. Can you try direct wired connection, see if you still see web socket success?
