Logging in into separate airlines

This might be just my problem;

But recently I've been having this problem where when trying to access a specific airline, such as one of my BQB Airlines, Aerolineas or La Compagnie airlines the web page won't log in. However, the forum etc works perfectly, but trying to access my airlines 70% of the time doesn't go through and says that the "login failed". 

As the screenshot shows, this same message appears very often. 

Is this just me or are other people having this problem?
