Hello,
After an upgrade, the web interface was inaccessible unexpectedly. I just wanna share a way to resolve this without a power reboot:
1. connect on you router with ssh (you should have ever configure this)
2. restart httpd service : /etc/init.d/uhttpd restart
3. check: /etc/init.d/uhttpd status
You should have your web interface up and running.
If you know another way to to this (maybe with sms command) let me know :)
Regards
Jerome
