Eu tenho uma versão portátil de um banco de dados MySQL que estou tentando conectar.
Em um computador em execução no Windows 10, posso me conectar a ele usando 127.0.0.1 na porta 3310.
Se eu copiar essa instância para qualquer outro computador que execute o Windows 10, posso me conectar usando o IP.
Quando copio a mesma instância para um VPS do Windows Server 2016, não consigo me conectar ao banco de dados usando o endereço IP; ele só se conecta se eu usar o host local.
Eu preciso conectar usando o endereço IP. Algumas pessoas me disseram que eu deveria ter um problema com meu arquivo hosts , mas é exatamente o mesmo em ambos os computadores.
Alguém tem uma ideia do que poderia estar causando isso?
--- ATUALIZAÇÃO 1 ---
Eu sei que localhost e 127.0.0.1 são quase iguais. Mas o problema para mim é que eu uso um software legado que aceita apenas o endereço IP, por isso não posso usar o host local.
Eu não consegui conectar o software ao banco de dados, então instalei o HeidiSQL e tentei conectar usando 127.0.0.1 e realmente não estava funcionando, então mudei para localhost e ele se conectou.
Desde que eu não posso mudar o software legado para usar localhost, eu preciso descobrir porque o MySQL não está aceitando conexões através de 127.0.0.1

# This is for a large system with memory = 512M where the system runs mainly
# MariaDB.
#
# MariaDB programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, do:
# 'my_print_defaults --help' and see what is printed under
# Default options are read from the following files in the given order:
# More information at: http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MariaDB clients

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
