[Swan] After upgrade, "No connection has been authorized with policy PSK+IKEV1_ALLOW" [SOLVED]

[Hugh Sparks]

For the sake of discussion and to rule out misunderstanding, here's my complete and working ipsec configuration file:

conn L2TP-PSK
         pfs=no
         auto=add
         ikev2=no
         ike=aes256-sha1-modp1024,aes128-sha1-modp1024,3des-sha1-modp1024
         esp=aes256-sha256,aes256-sha1,3des-sha1
         authby=secret
         type=transport
         left=24.196.53.220
         leftprotoport=17/1701
         right=%any
         rightprotoport=17/%any
         dpddelay=30
         dpdtimeout=120
         dpdaction=clear

I tried the suggested esp change:

     esp=aes256-sha2_512,aes256-sha1,aes256-sha2_256,3des-sha1

The connection loaded without error, but when I tested with both Windows and iPhone, the dread message returned:

     ...no connection has been authorized with policy PSK+IKEV1_ALLOW

I don't have an Android device on hand to test right now, but it would be great to have a "one-size-fits-all" solution.
(At least for common consumer devices.)

Thanks to all,
