It also connects to discord, supposed to be blocked since more than a week. No other device or browser I have connects to YouTube, they all get ERR_SOCKET_NOT_CONNECTED, and only a fresh Vivaldi profile on the same pc also connects to Discord, everything else get ERR_CONNECTION_RESET.

I’ve tried disabling all extensions, it still connects. Checked its IP address and DNS server and they’re the same as other devices/browsers. Any idea what could be going on?

24m edit: Discord just started working on some other chromium browsers including on another device.

80m edit: Another chromium browser just also connected. After deleting browser data it stopped

edit 3: found that if I add this to the servers section of a Network Persistent State file associated with a chromium browser profile (while the browser is closed), it can connect to youtube. Can’t explain why. (anonymization says https://www.youtube.com + some number that doesn’t matter in the beginning in base64):
{"alternative_service":[{"advertised_alpns":["h3"],"expiration":"13376788973168704","port":443,"protocol_str":"quic"}],"anonymization":["GAAAABMAAABodHRwczovL3lvdXR1YmUuY29tAA==",false],"server":"https://www.youtube.com","supports_spdy":true}

Edit 4: The block is gone

    Maybe do a trace with wireshark and compare the connection attempts?

    Most website blocks are done on a dns level, maybe vivaldi doesn’t accept the “wrong” dns replies, uses DNS-over-HTTPS or doesn’t query any affected dns servers.

      I have secure DNS set up on all my devices, this isn’t a DNS level block. I tried looking at the chrome Dev tools connection page and I would try wireshark too but idk what to look for, especially when I’m trying to figure out why it works

      Edit: I’m pretty sure with normal DNS you get a page saying it’s blocked for discord

      No change, vivaldi still connects other browsers still don’t

    Probably just uses a fallback DNS service when the “official one” fails

    I’d recommend to not use ISP DNS in general.
