本人使用squid 在aws服务器上搭建了代理服务，配置了账号密码的访问形式，但是经常出现 Cannot connect to proxy 、 timeout 的情况
请问是什么原因？
下面是我squid.conf 的配置信息
#
# Recommended minimum configuration:
#
auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/squid_passwd
auth_param basic children 5
auth_param basic realm Proxy Authentication Required
auth_param basic credentialsttl 2 hours
auth_param basic casesensitive off
acl auth_users proxy_auth xifarm runwulink
http_access allow auth_users

#
# Recommended minimum Access Permission configuration:

# Deny requests to certain unsafe ports
# http_access deny !Safe_ports
# Deny CONNECT to other than secure SSL ports
# http_access deny CONNECT !SSL_ports
# Only allow cachemgr access from localhost

# http_access deny manager
# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localnet
http_access allow localhost
http_access allow myip
# And finally deny all other access to this proxy
# http_access deny all
http_access allow all
# Squid normally listens to port 3128
http_port 0.0.0.0:3129
# Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /var/spool/squid 100 16 256
cache_swap_high 90
cache_swap_low 70
# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid
#
# Add any of your own refresh_pattern entries above these.

好问题！！抱歉我也不太懂，你问问chatGPT吧：https://new.quke123.com/
