TLSV1_UNRECOGNIZED_NAME(tls_record.cc:587)

Describe the bug

Hello and thank you for creating this application.

I cannot display dashboard for standard PiHole installation using FlutterHole over HTTPS with correct self signed certificates, using proper API credentials. Tried to turn the "allow self signed certificates" option to no avail.

The same dashboard is accessible on any browser from the same device on the same network pointing to the same https URL.

To Reproduce Steps to reproduce the behavior:

1. Go to 'https://10.11.11.10'
2. Tap on 'Dashboard'
3. See error

Expected behavior Ability to access pihole dashboard over https

Versions (please complete the following information):

• Pi-hole v5.1.2 Web Interface v5.1.1 FTL v5.2

• FlutterHole version: 5.2.3

Additional context This is over VPN. Certificates created using pfsense. Works everywhere else with no issues. I believe this is related to issue #84 possibly a duplicate?

Hello @aljazzair 👋 - Thanks for opening an issue!

The error (TLSV1_UNRECOGNIZED_NAME) seems indeed similar to the issue you referenced.

I will take a look at the SSL implementation of the app again (this tiny snippet).

As an idea, have you tried turning on the allowSelfSigned toggle, then kill the app, then restart it? Perhaps the app's client instance is not updated correctly in the linked snippet.

Hello

Thank you very much for taking the time to review and answer. I did follow your advice and it works. I am now able to open the application and view the dashboard on both my android devices :) I am now closing this issue.
