Have been on Zwift about 11 months with no problem. Over the past week have had issues with game freezing mid ride (between 7 and 30 minutes into ride) and becoming unresponsive. Log says :
[16:34:01] NETCLIENT:[WARN] UDP connection timeout (2 so far), reconnection attempt 2
[16:34:01] NETCLIENT:[INFO] Connecting to UDP server…
No other internet issues in the household. 100Mbs Fibre. Son playing on XBox or streaming NetFlix without issue.
Happened now 4x in 4 days of trying, so getting a bit annoyed.
PC: Surface Book 3 with plenty of memory.
Zwift : 1080p only so not really taxing the GPU and has been stable for 11 months.
I did notice in game that the numbers in Watopia had dropped from 6100 to about 5200 over the preceding 5-10 minutes before the last crash, so either others had an issue and dropped out or a huge event just finished!
