JOSM proxy settings is ""no proxy"". When I run JOSM, it couldn't work because of error ""java.net.SocketException: Network is unreachable"". I think the issue can be caused by some legacy code, which forces to use `AF_INET` instead of `AF_INET6` + `AF_INET`. I saw something similar with a Python code: https://github.com/platformio/platformio-core/pull/4151 But my internet connection works fine. Here is a `curl` examples: {{{ $ curl -vI https://josm.openstreetmap.de * Trying 2a01:4f9:2b:907::2:443... * Connected to josm.openstreetmap.de (2a01:4f9:2b:907::2) port 443 (#0) * ALPN: offers h2 … $ curl -vI https://github.com * Trying 2001:67c:2b0:db32:0:1:8c52:7904:443... * Connected to github.com (2001:67c:2b0:db32:0:1:8c52:7904) port 443 (#0) * ALPN: offers h2 … $ curl -vI https://api.openstreetmap.org/api/ * Trying 2001:978:2:2c::172:c:443... * Connected to api.openstreetmap.org (2001:978:2:2c::172:c) port 443 (#0) * ALPN: offers h2 … $ ping -c3 api.openstreetmap.org PING api.openstreetmap.org(2001:978:2:2c::172:d (2001:978:2:2c::172:d)) 56 data bytes 64 bytes from 2001:978:2:2c::172:d (2001:978:2:2c::172:d): icmp_seq=1 ttl=52 time=25.1 ms 64 bytes from 2001:978:2:2c::172:d (2001:978:2:2c::172:d): icmp_seq=2 ttl=52 time=24.5 ms 64 bytes from 2001:978:2:2c::172:d (2001:978:2:2c::172:d): icmp_seq=3 ttl=52 time=26.1 ms --- api.openstreetmap.org ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 24.538/25.274/26.145/0.662 ms }}} When I use ""report bug"", I see the same error.
