Some suggestions:

1. Stop posting these screenshots: they’re almost impossible to read. Try to make life easy for recipients if you want help. Instead, copy the text from the terminal and paste it into your post, or into an attachment. If you really need to show a screenshot, take a high-resolution image and attach the image file.
2. Make sure your log entries have timestamps. It’s impossible to tell whether all these things happened immediately consecutively, or spread out over time.
3. The error 1100 means what it says: TWS/Gateway has lost its connection to the IBKR servers. Therefore it can’t process API requests until that connection is restored. It looks like your request was submitted while the connection was broken, so of course you get an error response.
4. Note that the IBKR test clients are bare minimum demo code, and not production quality, so they don’t handle situations like this. When writing ‘real’ code, you have to pay attention to error conditions and act according – for example, don’t make API calls when there is no connection to TWS, or no connection from TWS to IBKR.
