The system detects when the local IP changes and updates DDNS for yourpersonalhash.unraid.net immediately.

 

If Remote Access is enabled, the system checks the WAN IP every 10 minutes. If it detects a change then DDNS for www.yourpersonalhash.unraid.net is updated immediately.

 

If you are not seeing the updates, it is likely the DNS server you are using is caching the results. Try using one of the big public DNS providers, like Google at 8.8.8.8

换了dns还是不行，我的服务器里点击远程登录无法联接，家里的公网ip己经改变，服务器端没有更新，还是使用以前的ip

 

[ Google Translate: I changed the dns and it still doesn't work. I can't connect by clicking on remote login in my server. The public network ip at home has been changed, and the server has not been updated. I still use the previous ip. ]

I'm glad it is working for you again.

 

I have a theory about what happened...

 

UpdateDNS.php runs every 10 minutes but it only sends data to our cloud server when it detects a change, plus a "keep alive" after three days of no changes, or if you run that `UpdateDNS.php -v` command.

 

If the issue is that the My Servers dashboard had the wrong url, then it seems like something must have gone wrong with the initial submission when the change was detected.  In that case, when we ran `UpdateDNS.php -v` it would have fixed the issue immediately. Or if we had done nothing, it would have fixed itself after about three days.
