ngrok with https on localhost returns 502

问题

I need to debug webhooks in an asp.net core 2 api hosted with kestrel. It only runs in https : https://localhost:44338 (accessible, works fine)

I thought ngrok would be fast to use but I'm always redirected to an error 502.

I've tried those conbinations I found in other posts:

ngrok http -region=eu -bind-tls=true -host-header=rewrite localhost:44338
ngrok http 44338 -region=eu -host-header="localhost:44338"
ngrok.exe http -region=eu -host-header=rewrite localhost:44338
ngrok tls -region=eu -hostname=localhost 44338

added to

netsh http add urlacl url=https://xxx.ngrok.io:44338/ user=everyone

but no change, any idea?

EDIT :

ngrok http -region=eu -host-header=rewrite localhost:8592
netsh http add urlacl url=http://xxxxxxxx.eu.ngrok.io:8592/ user=everyone

I've just found myself in the same predicament, I have a .net core 2.2 project using a Kestrel server which isserving up https on port 5001 (out of the box).

In order to get ngrok to work (version 2.3.29 - downloaded at time of writing as new PC which I've not used it on before).

Running simply just ngrok http https://localhost:5001 returned urls that I can now use to debug webhooks.

Hope this helps.
