Disconnected - Failed to connect to instance

Fairly frequently running into the title error, booting me back to the login screen when trying to enter a zone. Started a few days ago, was fine before then. Troubleshooting data below. From what I can tell the issue itself likely isn't something you can assist with, but the resulting error I think is something that I think might be fixable client side.

Basically, I'm seeing 15-20% packet drops on the way to the instance server. The part that feels like it might be on your end is that when this happens the connection attempt never tries again. If I don't connect right away, I always hit the full 15 second timeout.

Monitoring the latency with F1 it's 100% consistent, if there isn't a connection (latency goes from 0 to anything) in the first second it'll go the full 15 and time out booting me to the login screen. I have never seen a connection happen after the first second of the load screen. If I connect to the instance gameplay is fine, no latency spikes or anything. The problem is specific to connecting to the instance initially and if that attempt happens during one of the frequent drops in connection to that server I'll always time out to the login screen. This is especially problematic as it takes at least 3 loads to actually do anything (load to town, load to hideout, load into map). If any of those fails it's back to login to try from the start. I've tried using different servers, even international, no change.

If it attempted to connect again during that 15s timeout period, or if it just attempted the connection before the loading screen so I don't get kicked to login it wouldn't be as big a problem. Of course that's easy for me to say, I'm sure it's not that simple.

For what it's worth that 206.223.119.188 hop that seems to be the problem comes up a lot searching through PoE issues, and has for years. It's probably not something you can fix, but in case it helps here's some examples:

I know it's a stretch, but it really makes it hard to play with how often we load between instances. Even a 10% chance of this happening means tons of lost time, especially this league with the mirage being another instance. If there's anything else I can provide that would help please let me know!

I've been running into the same issue since we switched to T-mobile Fiber.

Despite our internet being terrible with our prior provider, this particular error/disconnect did NOT occur.

I have done the following to no avail:

Tried multiple game gateways.
Tried Vulcan, Direct x, etc.
Deleted all config/cache files for PoE.

flushdns, release, renew, netsh winsock reset, etc.
Firewall exceptions.
VPN on/off.
Wifi vs physical connection to router.

ISP replaced the router.
ISP changed router config to DHCP.
ISP inspected all the physical connections.

The issue persists. I have blazing fast internet speed for both upload and download, but the disconnects continue on instance loading.

I also ran WinMTR, and I was getting something like 50% packet loss...

At a loss at this point.

Same problem here. Sometimes it takes me like two or three minutes to reconnect.
It may work fine for hours then this starts happening.

I wish we had an option to stick to the same server when changing zones.

Unfortunately the only option i see for now is VPN.
