Does Fizz block port 25500/25000?

Hi Joäo

Please try restarting your modem.

If there is an issue, you can try a factory reset of the modem. Press and hold the small button on the back of the modem with a paper clip for 10+ seconds. Then wait 3-4 minutes before trying. You will have to re-enter the codes shown on the modem initially.

You can check the modem admin settings via your browser:
http://192.168.0.1/login.htm
user:cusadmin and your wifi password
Menu: Basic >> Port Forwarding

If the problem continues, you can contact customer support by chat:
1- Connect to your Fizz account by clicking « Login » in the top right corner at fizz.ca
2- Any ad blockers in your browser should be disabled.
3- Open a Fizz help page like this one: https://fizz.ca/en/faq/how-install-my-wi-fi-modem
4- The green chat bubble should appear after a few seconds in the bottom right corner.

Joäo, Fizz home internet and mobile services are not related.

This is possibly an issue with your device or with the software you want to use.

It's good to know you found a "temporary" solution using VPN.

They should work, try to reset your modem, it may solve your issue. Hope this helps.
