Hi there, I recently changed my network configuration and installed set of Mesh extender with one as router and another as satellite peer to replace the previous network router (which was changed to Modem mode only now). Now I realized I can still found the IP of umbrel home with Angrey IP scanner but I cant load the GUI on chrome nor can I SSH into the Umbrel home, I’m getting message as below: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the XXXXXXXX key sent by the remote host is SHA256:QVLTMzPR+o0XXXXXXXXXXXXXXXXXXDVhI0dHQ. Please contact your system administrator. Add correct host key in /Users/username/.ssh/known\_hosts to get rid of this message. Offending XXXXXXXX key in /Users/username/.ssh/known\_hosts:28 Host key for umbrel.local has changed and you have requested strict checking. Host key verification failed. Could anyone point me what I could do to fix the problem so I can access to the Umbrel home again? TIA, macanno ---

**Solution:** Remove the old SSH key: Run the following command: `sed -i '' '/^umbrel/d' ~/.ssh/known_hosts` Reconnect via SSH: `ssh umbrel@umbrel.local` Confirm the new host key. Access the GUI: `http://umbrel.local` 🕶 ---

Thank you so much for the advice. I managed to SSH into the umbrel home box now but [http://umbrel.local](http://umbrel.local) isn’t accessible. " This site can’t be reached, **umbrel.local** refused to connect." I tried using the IP directly (found via Angry IP scanner) still got the same issue Thanks in advance for any further advice. ---

Sometimes a reboot helps. Run: `sudo reboot` Then try accessing [http://umbrel.local](http://umbrel.local) again. ---

thanks for the previous advice. I can SSH into the umbrel home box and restart it with su reboot. however, I suspect the umbrel isn’t running the service as I cannot access the login page with either [http://umbrel.local](http://umbrel.local) or the IP address of the box. is there a way I can factory reset everything with Umbrel home?
