What should I do if my company cannot log on to the website background, but it can be done elsewhere?

You cannot log on to the background of a website in a company, but you cannot log on to the background of a website in another place. However, you can enter information on the page and click log on, the page jumps to the normal logon page and returns to the logon page. what is the problem ???? This is not the case outside of the company. from the description, contact your system administrator or DBA to check the next hop path, or the user Shield list is not allowed to log on to the website background at the company, but can be used elsewhere.
