wireguard-windows: Wireguard does not start a previously activated tunnel from time to time

[Jan Petrischkeit]

Hi,

thank you for this information, I will take a look at that. Now I know 
where to look.

However, I am using the "endpoint-by-dns" for a specific reason:
In my area there is an internet provider which uses carrier grade nat in 
a strange way, so that no rdp session can be created over a wireguard 
tunnel if the ipv4 address of the server is used as endpoint. I created 
a dns entry for the wireguard server, so that in these cases the ipv6 
address is used and the tunnel is established without the weird nat of 
the internet provider in between.
Since not all people here have activated ipv6 in their home routers or 
have always an ipv6 connection while traveling, I cannot simply use the 
ipv6 adress in the config.

Regards,
Jan
