公司的CRM系统登陆界面打不开，只针对我在的市区的电信网络，怎么回事

[没有工]

本月的15号还能上CRM系统，到了16号乃至现在，都打不开登陆界面，一直出错提示，别个地区的同事都用的好好的。
我用的是电信网络不管是adsl，还是其他的宽带，换了7个朋友的机子和网络，5家网吧，甚至是打电话让客服帮忙试网址还是都是同样的出错代码。由于公司的CRM系统没有维护专员，管技术的又休假，要命的经理催着输入信息。
不得不求救各位大侠帮忙看看了。高分献上求分析求解决。谢谢各位
出错提示窗口的信息是:
Unable to resolve expression 'checkUSBKeyContent()' for com.wisecrm.application.login.AppLogin@3b00c7[Home/crmLogin].

详细错误信息的内容是:

难道是数据库的问题。。。没看出来

[easyroom]

我推测你们是多个应用服务器，前面用DNS根据用户所在区域分流，也就是说你们区访问的服务器跟其他的服务器是不一样的。
可以让正常访问的同事ping一下你们系统的域名，看看跟你们区获得的IP是否一致
如果前面的推测是正确的。可以查一下15号发生过什么，重启应用，重新部署，替换class等

应急的话可以直接把服务器从网络断开，强迫你们区的用户去访问其他区的服务器

肯定是你们区的服务器有问题，和网络没关系

是USBKEY没插或者没插好，或者把USBKEY拔下来，重启电脑后再插上。
