It should work (works for me - see my output below). Perhaps its related to your saved state? If you also had another log like this before but with an invalid IP address it may cause this. Or your config.ini file does not contain proper masking instructions?

Starting Drain3 template miner
Checking for saved state
Saved state not found
Drain3 started with 'FILE' persistence
7 masking instructions are in use
Starting training mode. Reading from std-in ('q' to finish)
> connected to 10.0.0.1
Saving state of 1 clusters with 1 messages, 528 bytes, reason: cluster_created (1)
{"change_type": "cluster_created", "cluster_id": 1, "cluster_size": 1, "template_mined": "connected to <:IP:>", "cluster_count": 1}
Parameters: [ExtractedParameter(value='10.0.0.1', mask_name='IP')]

I added the 7 masking instructions are in use log print to master code, you can try to pull

Tks @davidohana You are right, it is related to the saved state.
