If you downloaded the MT Journal EA from MQL5 or from one of the older resource pages, that EA may still be trying to connect to the previous location and may no longer sync correctly.
Please go to the current free download page and install the latest MT4 or MT5 EA. After updating, make sure MetaTrader WebRequest allows: https://mt-trade-journal.com
Dashboard users can still log in from this page using the same email entered in the EA settings.
