I can not connect my second rig to the 4336/4337 port, while the first one works fine! I have setup the password as follows: f0=0;f2=0;f3=4;f4=3.1;f5=0 So it should switch between x11/x13. Again, it works fine on the first rig while the second rig (same btc adress, same password) can not connect to either 4336/4337 servers. Btw the second rig works fine when set to 3336/3337, but I would like for it to benefit from the switch function of the 4xxx ports too.
