Signal Subscription Failed whith an "unknown error"

[Eugen Funk]

Hi there,

I am getting errors when trying to subscribe to a signal.

The primary shown error is simply "Subscription Failed".

When I look into the journal, there is an "unknown error" logged.

This error occurs when I try to subscribe to the signal from different Brokers (RoboForex, ICMarkets - both demo accounts).

What could the the issue?

Thank you in advance

As it is not free signal so you should deposit money to your mql5 forum profile/account first, and after that - use it for subscription.

And check the subscription procedure in case you missed something:

The problem was my outdated MT5 version. After I managed it to install the new one, the MT5 servers "allowed" the subscription.

However, very strange behavior by simply "forbidding" the connection without a proper message... :(
