I have multiple problems. I have a static IP for my OMV (I am using raspberry pi 4 8GB), but I moved to another house and the router has a different IP now.
Because of that I can't connect to the OMV with the web gui. I could fix it using omv-firstaid, but I have another problem. My HDMI output doesn't work with my monitor (or with my older TV). So I can access the files only by editing them directly from the SD card. I can't use SSH or firstaid. I tried editing the config.txt (hdmi_force.... mode....), but the hdmi still doesn't working (the cable is good, I tested it). Can I edit a file to change my IP, or just set it back to automatic IP from the router? Or should I somehow connect it directly to my laptop with the ethernet and than could I use this connection to connect to it through SSH or web gui?
