I cannot Bid / Buy Players from the In-Game Ultimate Market

Hello, while I try to Bid / Buy Players from the In-Game Ultimate Market, I get this message "There was an error communicating with the Football Ultimate Team Servers. Please try again."

1st point :
I have never used bots and the proof is " my game is Standard Edition not Ultimate and as you know, Bots only works on Web app" so It means, I buy / Sell some players manually to get some Coins to can buy expensive and better players for my Squad. This is allowed according to rules as I used to do in all FC versions / platforms 

2nd Point :
I have never bought / Sold Coins from third parties and the proof is that I have purchased 30K Points so how logically I will care to buy / sell coins and I know It is illegal?. Also I'm an old player of EA. You can check the history of the following Emails :
