I have a problem with postgress, i changed in last days the IP of my
server and now I can't connect to DB. The server show me the next message:

for details

And my pg_hba.conf file this the next

# host       template1   192.168.12.10 255.255.255.255    md5

local    MyDatabase     127.0.0.1     255.255.255.0     password pass/pg_ltx
