As per RFC-1034 domain names must begin with a letter so my expectation is that you're trying to record an IP address or a domain which starts with a digit or something weird.

There are following workarounds:

  1. Use hosts file in order to give the host you're trying to record an alias which will not be in conflict with the aforementioned RFC-1034
  2. Use JMeter Chrome Extension as an alternative to JMeter's HTTP(S) Test Script Recorder

In any case I don't think you will be able to record WebSocket protocol, although it is HTTP-based but it's a different beast which cannot be handled by JMeter's HTTP Request samplers, you will have to mimic WebSocket traffic using JMeter WebSocket Samplers by Peter Doornbosch
