TeamViewer in MX23 fresh install not accepting incoming connections

#1 Post by joele »

So I have desktop, laptop and server, all were running MX21 with no issue with Teamviewer (version 15.42.4)

I have since done a fresh install of MX23 on the laptop and desktop (server still on 21 for now)..

Both the laptop and desktop I reinstalled teamviewer through the popular apps in package installer, it is version 15.43.7 on both. Configured the same on all 3 machines only allowing LAN connections (with password).

The Laptop and Desktop will make an outgoing connection without issue to the server but neither can accept an incoming connection from the other, it doesn't even come up with the password dialogue, just fails to establish connection.

The error in the logs is as follows - "CTcpConnectionBase[5]::HandleConnect: Connect aborted to dest-ip 192.168.1.72:5938 with error system:125."

Is this a teamviewer issue? something wrong in mx23? working for others?

In MX23, firewall is active by default :exclamation:

try with

Code: Select all

sudo ufw disable
If it is a firewall issue, here are the ports, you have to open for teamviewer
https://community.teamviewer.com/Englis ... ort-number
TCP/UDP Port 5938
TCP Port 443
TCP Port 80
kind regards

Awesome thank-you so much, easy fix, I clearly didn't think about firewall being on.. I opened the specific ports and all is good.
