Describe your issue

Hello, I have the same issue as here but I couldn’t find a solution to fix my problem.

Everything was working fine until a big blackout happened and since then the server is fighting me. I decided to redo everything from scratch (as I have the external storage with all the data). However during the post install I run into this error (present in the logs part of the text).

I checked my router settings and I should have fixed a IP for my server:

reserved list:
rpi

At this point I am wondering if the router is at fault, and If I need to buy one that support openwrt, and/or if I should buy a domain name.
