Every 50 maps my map is unenterable

Roughly every 50 maps If i try to enter 1 of the 6 portals i will disconnect failed to connect to instance.
If i start a new map everything is fine but i lose my investment
Ive tried restarting my router, changing dx12,11, vulkan
I've changed from lockstep to predictive and back again
I've changed all my graphics settings from high to low to medium
It's very frustrating to lose maps like this
