Hello, I have a strange problem.
I have installed the MetaTrader 4 platform using POL, everything seems to work great but when I attache an EA (Expert Advisor) on a chart, the EA tries to connect to a server, but it cannot make a connection.
In debug mode it gives the following message:
Error. Status code 505 returned.
I googled the error and I only found an HTML error 505, I don't know if this is what the debugger is posting, but it seems that the browsers within the virtual drive handle the http protocol well and they do not give me 505 error.
Any ideas?
Many thanks in advance,
D.
