[MacOS] VPN reconnects every 5 minutes

Post by mrazots » Sat Nov 23, 2019 8:46 am

Hello there! Im using Tunnelblick for OpenVPN configurations and a few days ago it started reconnecting every 5-10 minutes and then it can't connect to server and I have to choose different configuration. Also the same problem on my iPhone.

This is example of config file.

###############################################################################
# OpenVPN 2.0 Sample Configuration File
# for PacketiX VPN / SoftEther VPN Server
#
# !!! AUTO-GENERATED BY SOFTETHER VPN SERVER MANAGEMENT TOOL !!!
#
# !!! YOU HAVE TO REVIEW IT BEFORE USE AND MODIFY IT AS NECESSARY !!!
#
# This configuration file is auto-generated. You might use this config file
# in order to connect to the PacketiX VPN / SoftEther VPN Server.
# However, before you try it, you should review the descriptions of the file
# to determine the necessity to modify to suitable for your real environment.
# If necessary, you have to modify a little adequately on the file.
# For example, the IP address or the hostname as a destination VPN Server
# should be confirmed.
#
# Note that to use OpenVPN 2.0, you have to put the certification file of
# the destination VPN Server on the OpenVPN Client computer when you use this
# config file. Please refer the below descriptions carefully.


###############################################################################
# Specify the type of the layer of the VPN connection.
#
# To connect to the VPN Server as a "Remote-Access VPN Client PC",
# specify 'dev tun'. (Layer-3 IP Routing Mode)
#
# To connect to the VPN Server as a bridging equipment of "Site-to-Site VPN",
# specify 'dev tap'. (Layer-2 Ethernet Bridgine Mode)

dev tun


###############################################################################
# Specify the underlying protocol beyond the Internet.
# Note that this setting must be correspond with the listening setting on
# the VPN Server.
#
# Specify either 'proto tcp' or 'proto udp'.

proto udp


###############################################################################
# The destination hostname / IP address, and port number of
# the target VPN Server.
#
# You have to specify as 'remote <HOSTNAME> <PORT>'. You can also
# specify the IP address instead of the hostname.
#
# Note that the auto-generated below hostname are a "auto-detected
# IP address" of the VPN Server. You have to confirm the correctness
# beforehand.
#
# When you want to connect to the VPN Server by using TCP protocol,
# the port number of the destination TCP port should be same as one of
# the available TCP listeners on the VPN Server.
#
# When you use UDP protocol, the port number must same as the configuration
# setting of "OpenVPN Server Compatible Function" on the VPN Server.

remote 61.93.223.238 1194


###############################################################################
# The HTTP/HTTPS proxy setting.
#
# Only if you have to use the Internet via a proxy, uncomment the below
# two lines and specify the proxy address and the port number.
# In the case of using proxy-authentication, refer the OpenVPN manual.

;http-proxy-retry
;http-proxy [proxy server] [proxy port]


###############################################################################
# The encryption and authentication algorithm.
#
# Default setting is good. Modify it as you prefer.
# When you specify an unsupported algorithm, the error will occur.
#
# The supported algorithms are as follows:
# cipher: [NULL-CIPHER] NULL AES-128-CBC AES-192-CBC AES-256-CBC BF-CBC
# CAST-CBC CAST5-CBC DES-CBC DES-EDE-CBC DES-EDE3-CBC DESX-CBC
# RC2-40-CBC RC2-64-CBC RC2-CBC
# auth: SHA SHA1 MD5 MD4 RMD160

cipher AES-128-CBC
auth SHA1


###############################################################################
# Other parameters necessary to connect to the VPN Server.
#
# It is not recommended to modify it unless you have a particular need.

resolv-retry infinite
nobind
persist-key
persist-tun
client
verb 3
#auth-user-pass


###############################################################################
# The certificate file of the destination VPN Server.
#
# The CA certificate file is embedded in the inline format.
# You can replace this CA contents if necessary.
# Please note that if the server certificate is not a self-signed, you have to
# specify the signer's root certificate (CA) here.

Re: [MacOS] VPN reconnects every 5 minutes

There are various reasons which may cause the VPN to disconnect. Sometimes router firewalls cause the disconnection problems because Wi-Fi routers usually grind the VPN to a stop after a few minutes of use, plainly because they can't keep up with SPI / Firewall turned on.
