Hey David,
The EAs recognize the opened trade via the magic numbers, and they will continue managing the trades (with exit conditions). However, if the pause was long, it might be the case that the exit happened, and the EA will not close it because it is not at the moment.
If you have a good internet connection, it might be an issue from the broker’s server.
Try with another broker and see if it will happen simultaneously for both (if it happens, it is from your side).
