Sorry I haven't chimed in yet or responded to you I was a bit pre-occupied elsewhere for a bit. Exactly what afiadam described earlier happened to me similarly:
I've had a few times that I start making an entry, step away for a few minutes due to a phone call or something like that and when I come back I finish filling out the forms, hit save, and it redirects me to the login screen and all the info I typed was lost.
My install is on Debian 12 fresh with your new install script it worked out very well. I have cloudflare managing my domain but I've had the proxy feature off for the itflow. record so it exposes directly to the IP (By accident for some time) forgot to turn it on for this new install so we haven't been using the proxy.
I am using latest Google Chrome on Windows 11
This happened from my PC outside the network so using our public domain https://itflow.mydomainexample.com while logged in when that happened.
I haven't recently tested this again and my staff are just getting onboarded into ITFlow so I suppose I may have some more insight on this further a little later on if it happens again I can update you. The server Debian 12 is a VM in our oklahoma datacenter and sync'd to Central Time on the OS it seems like that date/time appears to be all good, just looked into that as well.
