Localtunnel: Crashes when data comes in

[mhornbacher]

When traffic comes in from the web the tunnel seems to crash

Error message thrown:

$ lt --port 2990 --subdomain jira-slack
your url is: https://jira-slack.localtunnel.me
C:\Users\mende\AppData\Roaming\nvm\v12.11.0\node_modules\localtunnel\bin\lt.js:81
    throw err;
    ^

Error: connection refused: localtunnel.me:43943 (check your firewall settings)

Notes

1. The server running on localhost:2990 (jira) does not receive any incoming traffic. Also this was replicated on 2 machines and 3 networks (1 commercial 2 residential) and the same error occurred on each one so it is likely not the firewall....
2. With the localtunnel running Jira cannot start as port 2990 is claimed, is this perhaps the problem in reverse? If so what is the point of localtunnel
3. Worked with Jira 7 a month ago

Details:

Port: 2990
OS: Windows 10
NodeJS version: 12.11
Server on Port 2990: Jira (atlas-run)

try running it via npx

npx localtunnel --port 2990 --subdomain jira-slack

🤷‍♂

I've had the same issue on my computer, and used this as a workaround

Thanks @jakubhomoly . Your solution worked for me.
