hi,all

I came accross usually the same questions recently, I had two mt4 platforms installed on my pc,I can use both of them last week,but I cannot login one of them suddenlly from Monday through my office network.the two mt4s are PSSmt4 and CSCmt4.

I inspected the two mt4 server IP as attachments.

and when I changed to another office location, the two mt4 works well. why?


any one can provide help, I appreciate it.

Firewall? I can't get a MT4 feed from work

If they are demos you might need to re-register as they usually have a time out feature
