"No network" error when attempting to connect to a local, non-public synapse server via HTTP

### Steps to reproduce

Basically, having the same issue noted in this error report below from a year ago. I would really like to have a way to work around this error. Being local only homeserver, I would like to avoid having to make SSL certs for a single user at this time. I have been able to link all other devices that are on iOS without issue. I receive the same "No Network" error, but no further information. The local network connection with this device works flawlessly otherwise.

My server address is: 'http://synapse.lan:8008'

I immediately receive a No Network error on Anroid only, exactly the same issue noted in the report below.

Thank you in advance.

### Outcome

#### What did you expect to happen?

_Similar to iOS, Windows and Linux applications, connection to server established, and moving to a login screen._

#### What happened instead?
I receive a "No network" error with no further error codes or reasoning. Rest of network connections aside from element-android work flawlessly.
