Also check the PC which access Unraid to perform update, its clock must up-to-date and internet aaccessable.

I checked my PC that I use to log onto my unRAID server and the date and time are correct. The date and time match when I log onto my unRAID (Dashboard on the unRAID and taskbar on my Windows 11 system).

I also have internet access on both the unRAID server and my PC.

SSL failure is typically bad date and time, but you can do a manual update:

https://docs.unraid.net/unraid-os/manual/upgrade-instructions/#manual-upgrade-or-downgrade

I really don't want to have to do a manual update every time there is an update. I would rather have the automated process work.

Is there any kind of log or something that shows what is going on behind the scenes to see what needs to be done to fix this?

SSL does appear to be working for other things:

Jul 3 05:02:09 JHBLZU1 sSMTP[3171993]: Creating SSL connection to host

Jul 3 05:02:09 JHBLZU1 sSMTP[3171993]: SSL connection using ECDHE-ECDSA-AES128-GCM-SHA256

Jul 3 05:02:11 JHBLZU1 sSMTP[3171993]: Sent mail for [email protected] (221 2.0.0 closing connection d75a77b69052e-4a7fc55bd7csm103779051cf.37 - gsmtp) uid=0 username=xxx outbytes=153636

I assume you are getting notification emails?

Yes. I receive 2 emails every day associated with the unRAID status and a rsync task that runs every day. I have another identical hardware unRAID server that is not having this update problem. It is on the same network.

If you are absolutely sure the data and time are correctly set, I would recommend retesting with a stock install , to confirm if it's a config problem. Backup the current one, then recreate it using the USB tool with a release older than 7.1.4, restore only the key, boot with it, and see if you can update the OS.

I am unclear on this process.

Do I recreate the current flash drive or do I use another flash drive?

If I use the current flash drive, will I loose the array and device configurations?

You mention to restore only the key but I have no idea where the key is stored and what name it is.

As an aside, the community application app says it cannot access github.com, no internet access. I ran the terminal and used date to check the time (correct) and ping and dig for github.com and both responded correctly.

Could this be a ssl certificate problem? Could my certificates folder be messed up, preventing https and ftps from working?

Either way will do for testing.

It's possible, the test above would confirm if it's a config issue.

Sorry for the delay. I was out of town for 2 weeks.

I created a new usb drive using the usb tool, choosing 7.1.2. I tried copying my current key and booting, but the boot failed with a key mismatch. I removed the key from the usb drive and booted, signing up for a 30 day trial. I was able to get into my unraid server and was able to upgrade the OS to 7.1.4. I reinstalled my original usb drive and rebooted. I tried to upgrade the OS but it still fails with the SSL date and time error.

Any suggestions?

If it works with a stick flash drive, it suggests a config problem with the current one, I assume it failed with the old flash using the current config?

Correct. I'll attach a new diagnostic file to have the latest settings.

If it's a config problem, you can redo the flash drive, backup the current one first and then recreate it using the USB tool and just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder (\config\plugins\dockerMan\templates-user), if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.
