I ordered internet about 2 weeks ago and have been using it since 17/11/2021.
Since yesterday I have a problem with the DSL connection.
At night it was a problem that resolved itself after 15 minutes.
This morning it was the same problem that I tried to solve for about 4 hours.

Information from: http://speedport.ip/
Internet:
No DSL tunnel
LTE tunnel ok
Hybrid bonding ok

 

For a short while everything worked fine [a few minutes], and now there is the same problem again.

I did a reboot to factory settings.
I unplugged the router for a few minutes, checked the cables and tried various options I found on the internet.
Router: Speedport pro plus

Tariff: MagentaZuhause XL with Hybrid LTE

Logs when the problem occurred and after reboot.
