Limit order placement always fail because of a "TechnicalError"

Good morning traders,

When I try to run my cBot on my account, it always fails to place the limits orders I want because of an obscure "TechnicalError".

What does this error mean exactly, and how do I fix it? There is no explanation message to help.

There no error in the Journal and this is what I get in the Log:

13/09/2021 07:45:00.332 | → Placing Limit Order to Buy 200000 AUDNZD (Price: 1,03365, SL: NaN, TP: NaN, ExpireTime: 20/09/2021 05:44:59) FAILED with error "TechnicalError"

I get this error for all my accounts: both for FTMO and for IC Markets.

Backtests and optimizations run completely fine.

Thanks!
