Obviously, your company has blocked the IP address of the stock software. Maybe the company thinks that your stock trading will affect your work. If you really want to access it, try to see if you can find a proxy server and access the stock software through the proxy

Is it true that only some colleagues can access it, but not other colleagues?

If one of your colleagues can use stock software and you are familiar with him

There are two ways:

1. Ask him to help Please help and talk to the network administrator, just open your IP address as well

2. Use your colleague's computer as a proxy server, and you can access it through him.

The method is: download the ccproxy software (this software is very rare, search it yourself, I won’t provide the URL), install it on your colleague’s computer, and set your IP address as a permitted account.

Then set the proxy server of the stock software to your colleague’s LAN IP.

If you want to set the IE browser to proxy through your colleague's machine: In the menu bar of the IE browser--Tools-Internet Options-Connection-LAN Settings-

In Tick ??"Use a proxy server for LAN", then click on the "Advanced" option and fill in your colleague's LAN IP and port number.

When you do not need a proxy, just uncheck "Use a proxy server for LAN".
