I've been using Ignition regularly for a couple of years now and in the past 6 months or so I've noticed an issue that I've never seen occur before. Every once and a while when working on a project in designer, I will try to save and instead receive a popup that says "Unable to save session props". I'm not sure what exactly triggers it, and it varies in frequency from gateway to gateway. It could happen never or within 2 minutes of opening designer. When it does happen, it seems like the only option is to restart the designer immediately to minimize the amount of work lost. Anyone have an idea of what causes this or how to stop it? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/3/f3ed30d555e4a50459d3fdd9f4a2c4827e6d2ae2.png) ---

Have the same popup after I update to 8.1.47, never seen before. ---

If you're on macOS, [this post](https://forum.inductiveautomation.com/t/ign-12611-basic-session-properties-gone-8-1-47/105231/5) may be related. @zac.orange, what OS are you running? and what version of Ignition? EDIT: actually I guess the dialog styling says it is Windows.. Ignition version might still be relevant though. ---

This happens to me as well, I'm on 8.1.47 in Windoze. I don't _think_ I've had the issues before in other versions ---

I find zero results when I search our issue tracker for "unable to save session props"... you've gotta open support tickets for these things. ---

Was there any solution to this on Windows? I'm running into the exact same issue; Windows 11 v24H2 Build 26100.3775 ---

Support told me that this will be fixed in 8.1.49 We have seen that this happens uppon ethernet to wifi reconection. Temporary fix: File \> Open Project \> Select same project ---

This problem happened when I was connecting to my Ignition environment through a load balancer. This error appeared whenever I tried to save after the load balancer redirected the connection. Seems like reestablishing the same session over a different connection could be the issue? ---

I’ve seen this occur intermittently. Have not been able to reproduce it in front of an IA agent when I have them on the phone.
