This happens to me all the time when I use Firefox (my preferred browser) while using the portal, to the point where if I know I’m going to be scening or doing something else somewhat time-intensive, like looking at jobs, I pull up Chrome, even though I don’t use it for anything else. I’m on my desktop at home with a wired connection. I just recreated the error by leaving the site up this morning for 20ish minutes or so. (I may not be grabbing the right bit from the browser console but those errors coincided with the timeout notification I got). If there’s any way to mitigate this on Firefox that’d be great, but cache clearing and various other things don’t seem to help.
