Probably, it is not the best option for you but I started using localtunnel instead of ngrok.
An installation and run flow is very simple:
npm install -g localtunnel
lt --port <your localhost port> --subdomain youruniquesubdomain
Then I can go to my http://youruniquesubdomain.localtunnel.me That's it!
An Incredible Update
I've found Serveo just now! And it is totally incredible! No installation, no signup!
All you need to do is to run this:
ssh -R <unique subdomain>:80:<your local host>:<your local port> serveo.net
like
ssh -R youruniquesubdomain:80:localhost:8000 serveo.net

No more free subdomain support from ngrok.....pls have a error as below
Tunnel session failed: Only paid plans may bind custom subdomains. Failed to bind the custom subdomain 'arvindpattartestfb.ngrok.io' for the account 'arvccccc'. This account is on the 'Free' plan.
Upgrade to a paid plan at: https://dashboard.ngrok.com/billing/plan
ERR_NGROK_313

It seems ngrok has completely dropped subdomains from free tier: https://ngrok.com/product#pricing
回答4:
You need to set up auth token you can find here https://dashboard.ngrok.com/auth. (W̶o̶r̶k̶s̶ ̶w̶i̶t̶h̶ ̶f̶r̶e̶e̶ ̶v̶e̶r̶s̶i̶o̶n̶,̶ ̶n̶o̶ ̶n̶e̶e̶d̶ ̶t̶o̶ ̶p̶a̶y̶ Apparently it's now paid feature, see ngrok pricing).
Then you can use it like this:
ngrok http 80 -subdomain yoursubdomain

simply for DHIS2 local installation i did this on termainl on ubunut server.
Make sure your web is running on the specified port . mine was on 8080 .
ssh -R dani.serveo.net:80:localhost:8080 serveo.net
The beauty of this serveo.net is you can resue the same hostname..prefix url before serveo.net as many time as you want , even if power goes off or internet diconnection.
cheers!

Though its not a solution but take it as workaround, I had the same problem while testing. What i did is keep the ngrok running with my http port, so my ngrok url is not changing. but I frequently changing and restarting my server for testing and debugging.
回答7:
You can use a custom subdomain without a paid plan, so long as you end your domain with .ngrok.io:
ngrok http 3000 -subdomain saxid-facebook-app-x9duw8b7.ngrok.io
Just be sure to pick something unique, because without a paid plan this subdomain isn't reserved and could still be taken when not in use.
