I am experiencing problems updating to the latest firmware, WB15-17051
No problems with wifi connection, connection to strava and komoot works fine.
Used wireshark to see what is going on, looks like a problem with communication between wahoo update server and bolt device using the ipv6 protocol. (Home network uses both ipv4 and ipv6)
Anyone seen such a problem?
Check how much memory you have available. I had this same problem a few years ago and it came down to having too many maps downloaded.
Good suggestion, did check that, Using the hotspot wifi via mobile works, so it is definitely something to do with an issue in the use of ipv6 between wahoo server and the elemnt.
