It's also possible it's the way your ISP is routing to their server(s)
My brother in law had this issue in PoE1 and I had it in PoE2 for 0.1
He called his ISP and that 'fixed it's for him a few days after and never had the issue.
My issue was caused by using a Wifi extender that I plugged my Ethernet cord into.
Once I switched to hardwired directly to my modem, all my problems went away for this issue, unless it was specifically on GGG's side (i.e server lag/too much traffic, etc.)
Lately when I get this, it's cause I have too much on my screen so I'll just exit to character creation and reload my character. Usually fixes it for me, unless it's just GGG servers like mentioned above.
Sadly I don't think there's really anything that can permanently fix this. Just temporary fixes on your end. I could be wrong, but from my experience you troubleshoot all your stuff and if nothing changes it's just the servers being crap at that moment in time lol
