Proxy is slow or not accepted

[Arturo99]

Hi
I have a dedicated proxy IP that i use that does not perform too well of late.
Connection is slowed right down.
Could this be due to my ISP or by google limiting it?
I have tried renewing and using a different ip but still gets poor results
Any suggestions?
thanks
Arturo

This can sometimes happen if one of the sides of the proxy is capable of IPv6 and the other isn't. Proxy connections are first tried over IPv6, and if that fails it downgrades to IPv4. If the proxy is running squid, you can force to try IPv4 first by adding the following line to the configuration file:

dns_v4_first on

Hi Lammert, which configuration file do i add it to ?
Is this a windows config or the s/ware using the proxy?

It is on the server side where the proxy runs. Depending on the distribution you should probably find the config in /etc/squid.conf, /etc/squid/squid.conf of /usr/local/etc/squid.conf
