issue with updating tactical rmm on its l;atest version v1.4.0 from v.1.3.1

Hi tactical-rmm team,

since the new update to version1.4.0 got out to release, i tried 3 times to update the app to the new version. As of now, all update trials of me gave out the same exact results! i am following both the backup taking and update procedures from the documentation of the app. The backup.sh is downloaded successfully, and i can see that the backup is indeed taken successfully! After that i am also downloading the update.sh script to install the upgrade, but the server is disconnected and it gives the error seen in the video. It needs to be mentioned that i am doing both actions using the tactical user and not a permissions user. Lastly, this is the second version i am trying to update, the first update, from the previous version to version 1.3.1 was done quickly enough and without any issues! the issue i am facing appeared now that i am trying to update from version 1.3.1 to version 1.4.0. Lastly, when i got back to tactical rmm portal now, i get the Backend is offline back seen in the second uploaded screenshot, and the only way for the portal to be accessible again, is after a restart of the server!

The recording i got cannot be uploaded, it consistently fails upload.

You started by being logged in as root, and in /opt/tacticalrmm/ which isn't a path we use. you should be logged in as tactical and in /home/tactical/ You've probably tried running the update scripts as root accidentally in the past.

You're getting permission errors on both backups and update about .sh writing being denied.

Do you even have a good backup somewhere? If you do, do a clean install, restore the server.

Then change all saved connection profiles to login via ssh to tactical and not root and never login to your server as root again. The install docs and other docs warn about this multiple times.
