Remote Connection not working with Sky ISP (UK)

Matt_Hutchinson · 2022-11-23T14:08:00+00:00

There was an error rendering this rich post.

My ISP is Sky (UK), I can receive an incoming connection with TeamViewer (someone can dial into me), I can then swap sides and see their screen, But I cannot instigater a remote connection to another machine in the first place

Bottom left-hand corner of TeamViewer first states "Connection to Partner" then "Connecting..." but does not continue onto the Password dialog

I have already opened ports 5938, 443 & 80 in my Firewall's Outbound Rules. I have given Teamviewer.exe write via the firewall. I have uninstalled/reinstalled, I am currently trying the latest inside build, but the issue exists with both released & insider. I have switched of IPV6

The software has historically worked perfectly, but in the last 'few' months, connection issues have started

Anyone got any ideas where I can go from here?

Some additional information

TeamViewer connects when I tunnel my internet traffic through a VPN to my office and effectively use the office’s internet connection (Zen Internet) which indicates the issue is a Sky's end

My laptop works as expected in the office, other locations, so again I believe the issue is with Sky

Using another laptop in the house give the same issues, so it’s not my hardware or software

While I appreciate the help, this question has nothing to do with Sky Remote Controls (your answer is about pairing the remote to the STB), it is relating to Teamviewer Remote Connections using Sky as the ISP

I'm glad someone else is having this issue! I support a fair few computers and have been having issues connecting to computers that are on Sky internet for a while now. I have spoken to teamviewer support on this and they don't have it as an issue. I cant believe there aren't more people having this problem and it hasn't been addressed. I have tried multiple computer and connections for the instigating connection but whenever Sky is the remote end, it just gets it stuck (after entering the password) on "initializing display parameters"

I know there was a similar issue with talktalk but you could just log in to your talktalk account and disable "scam protection" to resolve it.

Strangely, if I use **Third Party Product** to circumvent this issue, when the UAC pops up asking to allow **Third Party Product**, teamviewer kicks in and lets me put in the username and password but as soon as that is done, it drops the connection.

As I don't have Sky internet, I cannot speak to them so struggling to resolve.

Can anyone shed any light on this ?

This issue seemed to fix itself over the Christmas 2022 period, but has just started again

Last month, upgraded to FTTP ( Fibre to the Premises ) which required a new Router

TeamViewer working without issue for last month, but this morning ( 2023-05-17 ) the problem has started again.

It is NOT Router related, as it happens on more than one, not connection type as it happened on Copper & Fibre

I have discovered that when running WireGuard ( needed to connect to the office ) TeamViewer fails to connect ( doesn't get to the Password screen ) but with WireGuard deactivated, TeamViewer works as expected

IPV6 was switched off ( remember, TeamViewer has worked quite happily for months ), switching it back on seems to fix issue. WireGuard ( for unknown to me, technical reasons ) only works over IPV4 & switches of IPV6

Is there a REQUIREMENT for TeamViewer to work only via IPV6?

Why work yesterday, but not today???
