Gateway - Hummingbot client crashed after gateway relaunch on a change of config

[rapcmia]

Describe the bug

When testing https://github.com/hummingbot/gateway/pull/403 and accidentally added a wrong nodeURL using gateway config command, observed that after it reconnected and successfully updated the config and you happen to closed the gateway connection manually the connection to port 15888 is still active

• On the screenshot above, the gateway was already closed and run lsof -t :15888 to list where 15888 is active

• On the screenshot, observed that hummingbot crashed 539628 killed bin/hummingbot_quickstart.py -p a

Steps to reproduce

1. Update any config using gateway config and wait until it reconnects
2. On terminal, manually close gateway and run lsof -t :15888 to check if port 15888 still in use
3. Relaunch gateway and observe hummingbot client
