Environment:

I have similar error when i want to load a website where in local area network.
The error log is :
chromium: [ERROR:ssl_client_socket_impl.cc(959)] handshake failed; returned -1, SSL error code 1, net_error -201

I find around the network to resolve this problem, but i didn't find anything that is useful.

And i can't load https://bioconuat.cluster1.traform.io/TravoSSOAuthenticator?domain=biocon on webview too, but load on firefox(PC Ubuntu18.04) is success.

When i try to load it, error log change to :
chromium: [ERROR:ssl_client_socket_impl.cc(959)] handshake failed; returned -1, SSL error code 1, net_error -202

And i can load https://www.brrmedia.co.uk on webview.

//flutter code in webview():
