1/18/23 UPDATE:
As previously announced, we stopped renewing certificates for the unraid.net domain at the beginning of the year.
We had initially expected a grace period of a few months where the certificates would continue to work, but due to some necessary infrastructure improvements, the old unraid.net domain certificates are now invalid and will not work.
If you still need to migrate from the unraid.net certificate to a myunraid.net certificate, you may have difficulty accessing your server's webgui.
Actions for Unraid 6.10 or Newer:
If you can't access the server's webgui, use a local keyboard/monitor or SSH into the server and run 'use_ssl no'. (Note: if the system responds "command not found" then jump down to the section for Unraid 6.9 and earlier.)
Then, you can access the server via http://ipaddress (or http://ipaddress:port if you have defined a custom http port). Note: these are http URLs, not https URLs.
Navigate to the Settings → Management Access page in the Unraid webgui and click the "Upgrade Cert" button.
Click on the Certificate URL and verify you can access the server via the ipaddress.hash.myunraid.net certificate. You can change the "Use SSL/TLS" setting back to Yes or Strict if all is well.
Note: if you have a high-end router and previously added an exception to allow DNS Rebinding on the unraid.net domain, you will need to add an exception for myunraid.net. This feature is on/off on most consumer routers, so no additional changes are required to support the myunraid.net domain if the unraid.net domain works fine.
Be sure to update your bookmarks! The My Servers dashboard will automatically use the appropriate URL if you use the My Servers plugin.
Action needed for Unraid 6.9 and earlier:
Older versions of Unraid do not support the newer myunraid.net certificates.
You should be able to access the webgui using https://ipaddress (or https://ipaddress:port if you have defined a custom https port). Note that these are https URLs, not http URLs, so you'll need to ignore any browser warnings about invalid certificates.
Navigate to Settings → Management Access and set "Use SSL/TLS" to No.
Then, open a web terminal (>_) and type:
rm /boot/config/ssl/certs/certificate_bundle.pem
If you plan to stay on an older version of Unraid, uninstall the My Servers plugin, as it will be dropping support for older versions of Unraid. Warning: these older versions of Unraid are outdated concerning security updates and features, so we recommend taking advantage of our free upgrade policy and upgrading your system to the latest version of Unraid.
On Jan 1, 2023, we will stop renewing Let’s Encrypt SSL certificates on the unraid.net domain.
If you are still using a hash.unraid.net domain to access your server, please switch to the newer myunraid.net certificates that we provide for free.
The URLs used with these new certificates will provide increased privacy, particularly for remote access.
Upgrade actions for Unraid 6.10 or higher:
Navigate to the Settings → Management Access page in the Unraid webgui.
If there is an “Upgrade Cert” button, press it.
This will update the certificate and change your URL from hash.unraid.net to ipaddress.hash.myunraid.net.
You will need to sign back into the webgui with your root password afterward.
Note: if you have a high-end router and previously added an exception to allow DNS Rebinding on the unraid.net domain, you will now need to add an exception for myunraid.net. On most consumer routers this feature is simply on/off so no additional changes are required to support the myunraid.net domain if the unraid.net domain worked fine.
Be sure to update your bookmarks! If you are using My Servers, the My Servers dashboard will automatically use the appropriate URL.
Action needed for Unraid 6.9 and earlier:
Older versions of Unraid do not support the newer myunraid.net certificates, so if you don’t wish to upgrade Unraid you’ll need to navigate to Settings → Management Access and set "Use SSL/TLS" to No. Then open a web terminal and type:
rm /boot/config/ssl/certs/certificate_bundle.pem
If you plan to stay on an older version you should also uninstall the My Servers plugin as it will be dropping support for older versions of Unraid as well.
Warning: these older versions of Unraid are out of date with regard to security updates and features, so our recommendation is to take advantage of our free upgrade policy and upgrade your system to the latest version of Unraid. Then, switch to the myunraid.net certificate as described above.
Note: If you are unable to upgrade your certificate by Jan 1, 2023, the unraid.net certificate will continue to work for another 90 days, although at some point during that time it will expire and your browser will warn that it is insecure.
On Apr 1 we will shut down DNS for these certificates and the URLs associated with them will no longer work to access your server.
We highly recommend that you avoid this by migrating to the new certificate before Jan 1, 2023.
