Hi.
My wallet Electrum v.2.6.4 stopped sync now after the activation of SegWit.
I get the message "Server is lagging (23 blocks)".
How to solve this problem?
Go to the network settings and connect to another server (unticking select server automatically).
That'll probably fix it. Pick a server with the greatest block height (although the algorithm inside your electrum wallet is supposed to do this, it's not unlikely that it has failed after such an activation). It may also be useful to update to the greatest version from:
