  10. Updated the OpenSSL setting in response to new rules of Let's Encrypt certificates.
  11. Fixed an issue where there might be an incorrect IP conflict message for VLANs.
  12. Fixed an issue where DHCP settings of one network interface might be wrongly applied to another interface whose DHCP settings hadn't been enabled.
  13. Fixed an issue where CMS-managed servers might disconnect from a CMS Host that has been updated to DSM 6.2.4.

  24. Adjusted the fan speed on SA3400 and SA3600 to fix a potential overheating issue when E10G18-T2 is installed.
  25. Fixed an issue where users couldn't expand the LUNs on ext4 volumes that are already mapped to iSCSI Targets.
  26. Adjusted the fan speed to fix a potential overheating issue when a Synology network interface card (E10G18-T1, E10G18-T2, E10M20-T1, E10G21-F2, E25G20-F2) is used as the Heartbeat connection in an SHA cluster or for Open vSwitch.
  27. Fixed an issue where the system couldn't retrieve the full name of domain groups correctly after users click "Update domain data".

Things to note...

Following the UPS regression of DSM 7 is this:
  • Disables the "Shut down UPS when the system enters Safe Mode" option by default. <<< WTH?
As well as this "improvement"...
  1. Fixed an issue where the system might not obtain the compatibility information of hot-swapped drives on expansion units. <<< Has that ever been helpful?
 
I've asked Support and Tier 2 if this helps the DS CAM Login failures...
You've already posted this information. Please, don't post it in multiple threads. It is enough to only post answers from official support if you really want. That way threads won't get stuffed with useless information. Thank you.

I appreciate it... Was just nosy if anyone had tried it... I'm awaiting direction from Tier 2.

Just done the update and on my 718+ it doesn't say UPS shut down will not work, just it might not work.

Just done a check by unplugging the UPS waiting the allotted time, and the NAS shut down, then the UPS shut down, after plugging the UPS back in, both units started with no issues.

My UPS is a Cyberpower CP900EPFCLCD
 
Meanwhile I accidentally hit the bookmark for my main home NAS using the Let's Encrypt Synology.me external address. External access is off and so is QC and SSH for what it is worth. Somewhat surprised to see the page load from my holiday cabin wifi.

It appears off does not equal off when external access is actually triggered!
 
Wonder if this is exasperating the DS CAM Software fix that’s in the works?
Sorry I don't follow you. The reason for pulling the DSM update is given and, I get that it's really important to you, but I don't see mention of Surveillance Station or DS cam (note capitalisation of how Synology name their mobile app).
 
Latest DS Cam cam has a login failure problem. I might be testing experimental code later this week Based upon tests I just did.
it was seen in 6.2.3 & 6.2.4. And they had me install 6.2.4 Update 2 to see what would happen to symptoms. Login issue revolves around QC.

Please stick to the topic and don’t cross your problems into multiple threads. You have already been warned about similar behavior. This is the last warning. Otherwise, we will perform some actions with your account in accordance with our Terms and Rules and begin deleting unrelated posts.
 
This does look like a FUBAR moment with my NAS being externally reachable despite being configured to prevent this. Nobody likes to see unmitigated security issues either:

Abstract

Update to the Update quietly added to the release notes... Synology style.

If you've already updated. You're hosed. Still no fix.

There is now a new version of this update, as you say if you already updated I don't think you are able to install this update as it has the same version number.
