Connection to port 8080 in Iceland?

annerelbe

There's always this connection to port 8080 to a server in Iceland:

31.209.137.48:webcache               users:(("vivaldi-bin",pid=7287,fd=33))

inetnum:        31.209.137.0 - 31.209.137.255
netname:        IS-HRINGDU-NET1
descr:          Hringdu Business Customer & GGC
country:        IS

I have checked all the settings in Vivaldi and searched the Web for this connection but could not find any information. So, why does Vivaldi connect to this server in Iceland?

Hi, many servers of Vivaldi are in Iceland.
Vivaldi host sync, translation and mail server there if I remember correctly.

That's right. But "webcache" is a proxy service and I don't want to use a proxy service. And most of all I'd like my browser to not route web traffic through a proxy without my knowledge.

Hm, do you have preload enabled?
Check: chrome://settings/performance
By the way, Vivaldi doesn't route anything to third party companies except you have Web Store enabled.
This is for extension updates, for example.

No, preload is disabled.

Yes, and that would be this connection:

[xxx]:36956                   [2a00:1450:400c:c0b::bc]:5228          users:(("vivaldi-bin",pid=7287,fd=40))

inet6num:       2a00:1450:4000::/37
netname:        IE-GOOGLE-2a00-1450-4000-1
descr:          EU metro frontend

This is the connection to the Chrome Store. Still, the connection to the webache in Iceland is not related to this.

Then I have no idea, just block port 8080.
Maybe other users have more information about this webcache.

Cheers, mib

@annerelbe This is the server used for the real-time synchronization part of the Vivaldi sync service.

Pathduck

@thomasp So this?

https://stomp.github.io

According to the server certificate on ports 8080/61613 it's a host named stream.vivaldi.com

I don't get any connections to port 8080 here on Windows with Sync running. But I do see traffic to 61613:

$ tshark -i4 port 61613

In vivaldi.dll I find:
stomps://stream.vivaldi.com:61613/

So where does port 8080 come into play?

@Pathduck My guess is maybe chrome makes an initial :8080 connection (to check the server is alive or something) before switching to :61613 for data transfer?

Hi @Pathduck and @annerelbe

Both are used for sync notifications. We saw that differing operating systems are not able to use the same protocols in our first implementation of sync notifications.

To fix this we use two ports at the moment and it depends on your OS and Vivaldi version which one you use. (Both might be pinged in some versions) One of those ports will be phased out when we have aligned all the different OS's to use the same protocol.

I believe 8080 will be phased out as soon as we are confident that all OS's versions are working as intended using port 61613 for notifications.

This is seamless for our users but as you see, we have two ports there, but they only communicate with the sync notifications servers.
