Tunneling recommendations/guideline

Hello there!

I am trying to access my Mycodo dashboard/page from Internet. Due to ISP restrictions I can not establish any port forwarding or alike. After some research I came with this service pitunnel (www.pitunnel.com) that allows you to tunnel your external connection with raspberry.

I tested the service and it works for example deployments running on npm at port 5000, but it does not work when setting tunnel target to port 443 (mycodo is forced to HTTPS despite turning of the check mark on settings). When connecting I receive the following error:

I think the error can be related due to HTTPS issues on tunnel or SSL certificate not being valid.

Is there any workaround to use HTTP only or any other service recommended to achieve this kind of connection?

Thank you for your help and time!

I use frp and it works great.

This setting works fine for me. Have you restarted the frontend since changing the setting?
